Given you have two points and are asked to find the perpendicular bisector, what step should you do first?

• Skip the problem

• Find the distance between the two points

• Find the equation of the line

• Find the midpoint of the two given points

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
