Virtual Nerd: How Do You Find the Slope of a Line if You Have a Parallel Line?

What kind of lines have slopes that are the opposite reciprocal of each other? Parallel lines? No. Parabolas? No. Perpendicular lines? Yes! Watch and listen as the instructor demonstrates how to make these determinations about...

Given a line on a graph, what's the slope of this line? First, identify two points on the given line. Then, use a formula to find the change in y and then the change in x. This will be represented by rise over run. Watch this video to...

The teacher demonstrates how to plug in values from two given points to find the slope of a line. She uses the slope formula and goes through the problem step-by-step.

Tutorial illustrates how to find the slope of a line by first identifying two points on a graphed line then using these points to calculate the slope. [3:03]

So you have a transversal line intersecting two parallel lines and you are looking for a value that would make two corresponding angles congruent. You have all the information needed to write an equation to find the value. So write that...

The teacher demonstrates how to plug in values from two given points to find the slope of a line. She uses the slope formula and goes through the problem step-by-step.

Given a line, do you know how to find the slope? Yes, rise over run. Then all you have to do is plug in the given values and solve for the slope of the ramp.

The Fundamental Counting Principle can be used to find permutations. This tutorial will walk you through the steps with an example of finding the number of ways to rearrange the letters in the word NUMBER. [4:25]
