How To: Determine if a point lies on a line in standard form

In this video, we learn how to determine if a point lies on a line in standard form. In order to do this, you will need to substitute the X and Y value with the ordered pair that is given. The X value is the first number and the Y value is the second number. Re-write your equation, substituting in the numbers to the appropriate spots. Now, simplify the equation by doing multiplication with the negatives and positives (if given). When you get through the equation, you will end up with the solu...

Doug is using a large computer touch screen as his drawing board to show you how this process is done.

How To: Find if a point lies on a line in point slope form

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 ...

How To: Prove angle-side-angle congruency

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...

Hack Like a Pro: How to Conduct OS Fingerprinting with Xprobe2

Welcome back, my novice hackers! I've written a couple of articles on reconnaissance and its importance, and as I've said before, a good hacker will spend 3 to 4 more times doing reconnaissance than actually exploiting the system. If your recon isn't good, you'll likely fail, or worse—end up serving time and becoming Bubba's wife for a couple years. I can't say it enough—recon is critical.

How To: Choose the correct size for your snowboard

In this video, Sierra Snowboard gives us some tips on how to select the snowboard that's right for you.

One thing to consider is your bossy type. The weight of the rider is the primary factor in selecting the size of a snowboard. You'll notice that the height of a rider is not listed on a size chart. I...

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...

Move the ring until the magnetic needle is lined up with the orienteering arrow pointing north. Once they are l...

How To: Determine the age of a fossil using carbon-14

If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.

How To: Calculate your body mass index (BMI)

How do you know if you should lose weight is a question people often ask. For the most part the need for weight loss should be determined by how you feel in your own body. There are some calculations that doctors use to determine if you need to lose weight. One of those calculations is BMI or Body Mass Index. BMI is based upon a fairly difficult equation. BMI is figured by multiplying your weight by 703 then dividing by your height squared. A body mass index over 25 is considered overweight. ...

How To: Find your skin undertone

Starting by looking at your wrists if you look at the colors of the veins you can start to see what kind of undertones you have. If you have blue veins then it would be more cool, green veins would be warmer, and if you see both then you are more likely to be neutral. The next way to check is by holding a white piece of paper up to your skin so you can see in a mirror based on what color the paper looks like, is it reflecting? One of the final tips is whether you look better wearing gold or i...
