Please help me! Given triangle ABC with A(-4,-2), B(4,4), and C(18,-8) write the equation for the line containing the perpendicular bisector of segment AC in point-slope form. SHOW WORK.

On a phone here and no access to paper but you must first find the midpoint of AC which is the average of the coordinates. The perpendicular bisector will have a gradient that multiplies by AC's gradient to make -1. This will obviously pass through its mid point so as long as you know how to use y=mx+c you should be good.
