How to find the perpendicular bisector of segment AB if A (-2,4) and B (4,0)

Answer 1

a perpendicular bisector to that segment AB, will be another segment that makes say 90 degrees so

Answer 2

bisector -> find the midpoint. M=(1,2) is one point on the perpendicular bisector.
perpendicular -> slope of AB=-2/3; slope of perpendicular line=3/2
y=mx+b
y=3/2 (x-1)+2
