Find the Slope of the Perpendicular Line to the Line Through the Two Points (1,1) , (-1,7)

Math
(1,1) , (-1,7)
Slope is equal to the change in y over the change in x, or rise over run.
m=change in ychange 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 rise).
m=y2-y1x2-x1
Substitute in the values of x and y into the equation to find the slope.
m=7-(1)-1-(1)
