The perpendicular bisector of the line segment connecting the points (-3,8) and (5,4) has an equation of the form y=mx+b. Find m+b.
First find the midpoint 1, 6
find the slope between the lines (y1-y2)/(x1-x2) = -1/2 perpindicular slope = 2
point slope form y-6 = 2(x-1) re=arrange
y = 2x +4 continue.....
