Summary

The slope of a line is given by the change in over the change in between two points on the line. In other words, the slope of a line is equal to the rise over the run of the line.

Variable Description
The change in
The change in
The coordinates of the first point
The coordinates of the second point

Usage

To calculate the slope of a line between two points, calculate the change in y over the change in x. For example, given the two points (1,1) and (3,2) on a line shown below:

Example Line

The slope is equal to the rise over the run between the two points, which is equal to .
