Learn how to write the equation of a line given two points on the line. To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. An equation in the slope-intercept form is written as y m x b Where m is the slope of the line and b is the y-intercept.
Slope intercept line equation.
Now consider the x-intercept. The definition of slope is the rise divided by the run written as. To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. Pick any two coordinates.
