Question 871120
There are several steps to solving this problem.
Find the slope of the line that connects the two points.
find the slope of a line perpendicular 
Find the midpoint of the line segment.
Find an equation of a line that goes through the midpoint and is perpendicular
using the point and slope

y = -(4x)/3-7/3
slope =-4/3
perpendicular slope is 3/4
midpoint (-1, -1)
y=mx+b
-1=-3/4*+b
b=-1/4
y=3x/4-1/4
