Question 262830
step 1 - find the midpoint of the coordinates. We get
mp = ((2-2)/2, (1+3)/2)
mp = (0, 2))
step 2 - find the slope as
m = (3-1)/(-2-2) = 2/-4 = -1/2
we want the perpendicular slope so we take the negative flip of this to get
m = 2
step 3 - write the equation as
y-2 = 2(x-0)
or
 y = 2x + 2
