Question

 

write the perpendicular bisector of the segment (1,1) and (3,1)

Answer 1

a(1,1) and b(3, 1)   Find the perpendicular bisector

find the slope M = (Ya - Yb)/(Xa - Xb)

M = 1 - 1/1 - 3 = 0 This line goes right to left parallel to the x-axis at y = 1

The midpoint is (1-3/2, 1-1/2)

                         (-1,0)

The perpendicular bisector is a line that goes up and down along x = -1
