Lesson Summary:

In this video, we learn how to find the slope of a line by looking at a graph. We are reminded that the slope is just a number and is negative when the line slants from left to right like going downhill. We are then given multiple examples of finding the slope between two points on a line and reminded that it doesn't matter which two points we choose. The video ends by showing us how to find the slope of a horizontal and vertical line and prepares us for the next video on computing slope algebraically.

Lesson Description:

This is a continuation of the ideas presented in part 9, and continues to cover the basic idea of slope, what it means, and how you can determine the slope by looking at a graph. More examples are included. This is part 10 of a series of videos about graphing lines.

    This video shows more examples of finding the slope of a line by picking two points from the line and using the formula rise/run. All steps for finding the slope are explained. This is great practice for finding slope.
