Answer:
Hi,
Explanation:
We don't use A !
"Perpendicular bisector is a line that divides a given line segment exactly into two halves forming 90 degrees angle at the intersection point."
B=(-2,1)
C=(4,2)
M=middle of [BC]=((4-2)/2,(1+2)/2)=(1,1.5)
Slope of (BC) = (2-1)/(4-(-2))=1/6
Slope of the perpendicular bisector= - 1/(1/6)= -6
Equation of the perpendicular bisector:
y-1.5=-6*(x-1)
or y=-6x+6+1.5
or y=-6x+7.5
