Find the Slope 
(−1, −2) , (3, −1) 
Slope is equal to the change in y over the change in x, or rise over run. 
 change in y 
m = ---------------
 change in x 
The change in x is equal to the difference in x-coordinates (also called run), and the change in y 
is equal to the difference in y-coordinates (also called r ise). 
 y2 − y1 
m = -----------
 x2 − x1 
Substitute in the values of x and y into the equation to find the s lope. 
 m = −1 − (−2) /3 − (−1) 
Simplify the numerator. 
 Multiply −1 by −2. 
 m = −1 + 2 /3 − (−1) 
Add −1 and 2. 
 m = 1/3 − (−1) 
Simplify the denominator. 
Multiply −1 by −1. 
 m = 1/3 + 1 
Add 3 and 1. 
 m = 1/4
