How To: Understand parallel and perpendicular lines

In this video the instructor talks about parallel and perpendicular lines. Parallel lines are lines whose slope is the same. Now take the equations of a couple of parallel lines. Graph those lines on a coordinate axes and you can see that the lines are parallel to each other and never intersect each other. Perpendicular lines are those whose product of slopes is negative one. Perpendicular lines intersect each other and they make a perfect 90 degrees with each other at the point of intersecti...

And finally select the ink in pencil mode and draw a ...

How To: Graph a system of linear equations

Given a equation of a line, you can graph the line. A system of equations is nothing but equations of more than one line. In a single equation all the points that lie on the line, satisfy the equation of the line. Similarly a solution of a system of equations is points that satisfy each and every equation of that system. A system of equations can have a single point as solution when the lines intersect at a common point, or have a unlimited points in solution when the lines overlap on each ot...

How To: Graph a line using points and slope

Given a point through which a line passes and the value of its slope you can graph the line. To do this first plot the given line. Now taking the slope and using the rise over run method plot a second point. Connect these two points and this gives you the graph of the line. Extend this line further on both sides to get the complete line. The point where this line cuts the x-axes is called the x-intercept and the point where this line cuts the y-axes is called the y-intercept. The important po...

How To: Use and find x & y-intercepts in algebra

A straight line can be represented in the form of a liner equation containing two variables x and y. When the equation is graphed on a pair of coordinate axes, the line passes cut through the axes in two points. The point where the line cuts the x-axes is called as its x coordinate and the point where the line cuts the y-axes is called as its y coordinate. In this way a line has x-intercept and y-intercept. The x-intercept of a line lies on x axes and is in the form (a,0). Similarly the y-int...

How To: Draw a hypercube

This clip shows how you can draw a hypercube, which is a complex shape composed of cubes. You start with a series of equally spaced horizontal lines. Then you draw a vertical line from the origin (o, o, o). From the same point, you draw a horizontal line of the same length and two more lines at 45 degrees and 135 degrees from the horizontal. The vertical line and the 45 degree line form two of the vertices of one of the cubes. The vertical line and the 135 degree line form two of the vertices...

How To: Determine if lines are parallel or perpendicular

In this tutorial, we learn how to determine if lines are parallel or perpendicular. You will be given two straight line equations. First, remember that parallel lines have equal slope, identical to each other. Perpendicular lines have negative reciprocal slopes. For example, 2/3 and -3/2 would be a perpendicular line. If you think of parallel lines, then you can graph them to see what they look like when written down. Then, graph the other lines to see what they look like as well. Once you un...

Label the vertical with the temperatures(10, 20, 30...50) and the horizontal line with the days of the week(Monday....Friday). Label the vertical line as 'Temperature' and the horizontal line with 'Day of the week'. Plot the temperatures selecting the day from the horizontal line and marking at the c...

How To: Find the equations of parallel and perpendicular lines

A pair of straight lines can be parallel lines or perpendicular lines or neither. Two lines are said to be parallel when their slopes are equal. Two parallel lines never intersect each other. On the other hand two lines are perpendicular when the product of their slopes is equal to -1. Two perpendicular lines intersect only once and at right angles. So when you are given two lines and asked to find if they are parallel or perpendicular lines, first compute the slope of the lines. Identify two...

How To: Tie double fishing line

Attention fishing junkies! In this video learn how to tie a double fishing line with help from charter fishing expert Mark the Shark. Tie a double fishing line by making 30 turns with the line before tying the line off. Learn with this video demonstration the importance of a double fishing line, as well as the importance of keeping the fishing line taut.

How To: Find the equation of a perpendicular & parallel line

This video shows how to find the equation of the line perpendicular and parallel to a given line. The video starts off with an example, given the lines and the slopes (m). When 2 lines are parallel to each other, they have the same slope. When 2 lines are perpendicular to each other, the slopes multiplied together will give -1. Knowing these rules, the tutorial maker provides an example with numbers. He then leads each step of the process. Each step is written out in either black, red, blue o...

How To: Find the equation of a perpendicular line easily

In this video the instructor shows how to find out an equation of a perpendicular line. If you need to find the equation of a line passing through the given point and is perpendicular to another line, the first thing you need to do is compute the slope of the given line. Obtain the slope of the equation by writing it in the form of y = mx + b. Now the product of slopes of two perpendicular lines is a negative one. So the slope of our required line will be the negative inverse of the slope of ...

How To: Replace fishing line on a reel for deep sea fishing

Mark the Shark demonstrates how to replace fishing line on a reel for deep sea fishing. First make sure to thread the fishing line into the guide ends and that you don't miss any. Put the rod in the rod holder so that you have two free hands to work with the line. Thread the line twice in the spool and make a knot to hold the line in place. Pull the line tight so it's snug against the reel and snip off the loose ends. Turn the crank and make sure that the line feeds into the spool very evenly...

How To: Use line segments in pre-Algebra

This video shows the way to name a line segment. A line segment begins and ends with an end point. We can name a line segment by naming the two end points of the line segment. The example shown in the video shows a line segment that ends with points named 'A' and 'C'. So, we can name this line segment as segment 'AC'. This can also be named as segment 'CA'. The example shown consists of a point 'B' in between 'A' or 'B'. We cannot name the line segment as segment 'AB' or 'BA' and segment 'BC'...

How To: Find the equation of a perpendicular line

In this video the instructor shows how to find out an equation of a perpendicular line. If you need to find the equation of a line passing through the given point and perpendicular to another line, the first thing you need to do is compute the slope of the given line. Obtain the slope of the equation by writing it in the form of y = mx + b. Now the product of slopes of two perpendicular lines is negative one. So the slope of our required line will be negative inverse of the slope of given lin...

How To: Find the equation of a tangent line

This is the video about how to find the equation of a tangent line. As you may recall, a line which is tangent to a curve at a point a, must have the same slope as the curve. Therefore, the slope of the tangent is m = lim f(a + h) - f(a) h-->0 h Since the slope equation of the tangent line is exactly the same as the derivative definition, an easier way to find the tangent line is to differentiate using the rules on the function f. For example, Find the slope of a line tangent to the function ...

How To: Draw a perpendicular line from a point not on line

The narrator in this video shows you how to accurately make a line that is perpendicular to a given line using a compass. This technique involves using a compass to create two points on a line, which will be used to mark an "X" above the given line. Afterwards, all that is needed is to connect the points to create the line.
