The Slope of a Line

In this lesson I will teach you about the slope of a line.  We will be using the slope of a line all though this chapter so you really need to master the procedure I’m going to teach you in the lesson.  Basically, the slope of a line is a fraction that expresses the “angle” or “steepness” of a line.  The slope is represented with the variable “m” and we define the slope as the rise over the run of a line.
