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.

Note: The perpendicular bisector of the line segment $$\overline{AB}$$ is the line that passes through the midpoint of $$\overline{AB}$$ and is perpendicular to $$\overline{AB}$$.

Midpoint = (-4,6)

Slope = (4 - 8)/(-3 - 5) = 1/2

Perpendicular bisector: y - 6 = -2(x + 4) = -2x - 8

==> y = -2x - 2

m + b = -4
