In this lesson, we learn about the concept of slope and how to find the slope of a line by looking at its graph. The slope is a number that measures the slant of a line and is represented by the letter M. Depending on the slant of the line, we can determine whether the slope is positive, negative, zero, or undefined. We can compute the slope by using the idea of rise over run and choosing any two points on the line.
This covers the concept of slope, what it means and how to find the slope of a line by looking at its graph. This is part 9 of a series of videos about graphing lines.
