This tutorial will show you how to determine the slope of a line if you are given two coordinates on a coordinate plane. You should first find the location of each point on the plane, remembering that the coordinates are in the format of x-axis (or horizontal movement), followed by y-axis (vertical movement). After plotting both these points, you should draw a straight line between these two points and then determine the slope of this line by taking the rise over the run of the line.

In Ableton, you can set follow actions to tell clips to do something on a timed basis. The time can be immediate or random, but it is automated. This is more efficient than doing the follow actions manually. Go to clip view, type "L". This launches the settings which gives the space of time in which the follow action happens. You can set more than one follow action. You can determine when and how often the action will take place. You can determine when the clips occur automatically. The clips...

RichPin shows how to identify a rear axle on a Jeep Grand Cherokee to determine the correct replacement part. The first thing to do is to identify the axle by cleaning the fill plug on the back cover. Look at the inscription of the plug to find out the style of the rear end. In this example, Rich has a "Dana" style rear end. To determine if it is a 35 or 44 Dana, look at the web area to the right of the plug to locate the number. The two steps outlined in this video allow you to identify the ...
When defining fields in FileMaker Pro 10, one has to choose what type of field to decide for a database. There are two fields that accommodate special handling of data. They are time and time stamp fields. When one decides a field under manage>database,there is a option for "type". Under that, there is time and time stamp. The "time" one determines the time while the "time stamp" determines the time and date. This will help in preparing a proper and detailed database system.
Dougsimmsonline shows how to determine whether or not 2 triangles are similar. Not only does he go on to show that they are but he describes step by step how to do the math to find missing angles. He does this process twice to show one set of triangles being similar and show the other set of triangles as not being similar. Doug is using a large computer touch screen as his drawing board to show you how this process is done.
In this tutorial, the author shows how to determine if a point lies on a given line which is in Point Slope Form. To show the method he takes a sample point order pair and an equation of a line in its point slope form. Now he substitutes the value of the x, y order pair and the equation of the line, and solves the equation on both the sides. If both sides match it means that the point lies on the given line, or else it does not lie on the current line. In this video, the instructor shows how ...
This is a tutorial about how to prove the congruency (equality) of two triangles when the values of two angles and an included side of each triangle is given. The author of this video instructs the viewer that it should be first determined whether the values of two angles of one triangle are the same as those of two angles of the other triangle. Then one must seek to determine the equality of sides included in those angles in both the triangles. When it is found that these three values in one...

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...
In this video, we learn how to understand and determine equivalent fractions. If you have an equation with an equivalent fraction, you will first multiply the first numerator by the second denominator. Then, you will divide this answer by the denominator of the first fraction. After you do this, it will give you the correct answer. You can also do the reverse multiplication for this to check your answer and make sure you are correct. You can get an answer no matter what the numbers in the equ...
This video shows you how to milk a cow with your bare hands. Wipe the udder with alcohol based wipes, to make sure it is clean. Place your stool at the side of the cow, towards the back end. Remove a little wax from the teats before starting. Squeeze the teats firmly with a regular motion. A cow should be milked twice a day. If the udder is pendulous then use a flatter pan rather than an milking bucket. The richness of the pasture will determine how much milk the cow delivers. Rainfall and th...
Viewers learn that a net is the shape formed by "unfolding" a 3-dimensional figure, so a net shows all the faces that make up the surface area of the figure. Viewers are then asked to determine what type of 3-dimensional figure can be made from a given net (note that a cylinder has 2 circular bases, a pyramid has triangular faces, a cone has 1 circular base, and a prism has rectangular faces). Students are also asked to determine if a given net can be used to make a cube. This video will bene...

Parts of a compass include the ring, the orienteering arrow, magnetic needle, direction of travel arrow and declination scale. First, hold the compass out in front of you, making sure you hold it level. Move your whole body and point the direction of travel arrow to the object that you want to reach. Move the ring until the magnetic needle is lined up with the orienteering arrow pointing north. Once they are l...
ExcelIsFun shows you how to detect if a cell has a number or text. The first thing he explains is to find out what are the different types of things that can go into a cell. Next he talks about the use of "OR" and "IsNumber" to make it possible to determine if a cell has a number or text entered into it. The user then explains why certain rows where either "True" or "False". After watching this video, you should be able to determine if a cell is using text or a number.
