Example 4: Writing Equations of Bisectors in the Coordinate Plane A. Write an equation in point-slope form for the perpendicular bisector of the segment with endpoints A(-1, 6) and B(3, 4). Step 1: Find the midpoint. Step 2: Find the slope of the perpendicular bisector (opp. reciprocal) Step 3: Write in point-slope form (use the midpoint as a point)
