Perpendicular Bisector Equations

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 distance and midpoint to find the equation

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

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