Midpoint and Perpendicular Bisectors

Write the equation of a line PERPENDICULAR to y = -2x + 1 and passes through the point (2, 3).

Which equation is perpendicular to x = 7 and passes through (-4,9)

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

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
