Perpendicular lines have a negative reciprocal slope. Slope of y=2x+5 is 2/1 negative reciprocal is (-1/2)
Points: (-4, 8) and (0, -2) Midpoint: (-2, 3) Slope: -5/2 Perpendicular slope: 2/5 Perpendicular equation: y-3 = 2/5(x--2) => 5y-15 = 2x+4 => 5y = 2x+19 Therefore perpendicular bisector equation in its general form: 2x-5y+19 = 0
