This tutorial takes us a little deeper into linear equations. We will be looking at the slope of a line. We will also look at the relationship between the slopes of parallel lines as well as perpendicular lines. Let's see what you can do with slopes.

In this tutorial we will explore the slope of the line. Basically, the slope of the line measures the steepness of the line. We will start with some visuals to help you understand what the slope of a straight line tells us about the line.
