The slope is equal to the rise divided by the run. Start at a place on the equation line where the equation line runs through the intersection of two grid lines, then run to the right until you are below or above another exact intersection of the equation line and the grid lines, and rise (or fall) to the equation line. The number of squares risen (or fallen) divided by the number of blocks along the run is the slope.
The following animation illustrates rise and the run. Click on the graph to start the animation. The value of the rise (or the run) can be changed to examine the slope of other equations. This example uses equations of the form y = m x where m is the slope.
