The equation of the perpendicular bisector of the line segment joining the points (-3,8) and (-5,4) is 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}.
i know m = 2 but how about b?
