If you found the midpoint of line segment AB, what should you do next to find the equation of the perpendicular bisector?

• Use the midpoint and one of the points from AB to write the equation

• Use the midpoint and slope perpendicular to AB to write the equation

• Use the distance and midpoint to find the equation

• Skip it and hope it's not a test question

Write the equation of the perpendicular bisector of the line AB given:
A(3,-3) & B(1,-1)

• y = x - 4

• y = x + 4

• y = 1/2x -4

• y = x + 2

Write the equation of the perpendicular bisector of the line AB given:
A(1,3) & B(-3,5)

• y = 2x + 4

• y = 2x + 6

• y = -2x + 6

• y = 2x - 6
