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.

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:

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