Start with the original expression.
Use the Distributive Property — multiply 
by both 
and 
.
Combine the like terms — add up all the constants.
Reorder the terms.
The rise is the vertical distance between the two points, which is the difference between their y-coordinates. That makes the rise y2 − y1. The run between these two points is the difference in the x-coordinates, or x2 − x1.
So, the answer is very simple you just wanna, then, and then you have your answer
