Find the slope of a line through each pair (8,10), (-7,14)

First u have to find Y2-Y1/X2-X1, so u will replace the number to the y and x value.

step1: subtract Y2 and Y1. then find the different of x_value, which is 14-10/-7-8

step2: after u find the differences, u will get 4 / (-15).

finally, you will get a slope. y=4/-15x+b.
