Question

The coordinates of P are (-2,5) and the coordinates of Q are (6,1)

(C) What is the equation of the perpendicular bisector of PQ?

Answer 1

figure out the midpoint of that line (is it 2,3?

then figure the slope of that line (change in y/change in x)

take the negative reciprocal of that slope, that will be the slope of the perpendicular
y=mx+b
Put in the midpoing (x,y), and the slope of the perpendicular, and solve for b.
YOu now have m, and b
