Write the equation of the perpendicular bisector of the line AB given:
A(3,1) & B(-3,6)

• y = -5/6x + 7/2

• y = 6/5x + 9/2

• y = 6/5x + 7/2

• y = -3x - 5

• y = -3x + 1

• y = -3x + 13

• y = 3x + 1

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
