What is the equation of the perpendicular bisector of the segment joining points A(1, 1) and B(5, 7)?
Hint: Remember, a perpendicular bisector intersects the midpoint of AB
A. y = 2/3x - 6
B. y = -2/3x + 6
C. y = -2/3 + 2
D. y = -3/2 + 9
+5265 Use the slope formula to find the slope that is perpendicular.
Remember the slope formula is y2-y1/x2-x1.

6/4=3/2.
The OPPOSITE RECIPROCAL of 3/2 is -2/3, so the answer must be B.
