Use the given y-intercept for b the constant in the equation. How Do You Find the Slope of a Line from a Graph. A line with a positive slope m 0 as the line above rises from left to right whereas a line with a negative slope m 0 falls from left to right.
In this tutorial youll see how to use two points on the line to find the change in y and the change in x.
Arrange the slopes from flattest to steepest. In the slope-intercept form you use the slope of the line and the y-intercept to express the linear function.

The change in is equal to the difference in x-coordinates also called run and the change in is equal to the difference in y-coordinates also called rise.
