Parallel Perpendicular or Neither with Coordinates

Two rays, lines, or segments that form a right angle.

• Perpendicular Lines

• Parallel Lines

• 90 degrees

• Coplanar 

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

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

What is the equation of a line that is perpendicular to the line y = 3x + 2 and goes through the point (3, -4)?

• y = 3x - 2

• y = -1/3x - 5

• y = 3x - 4

• y = -1/3x - 3

Points A(1,3) & B(-3,5) are the endpoints of a chord on a circle with centre not at the origin. What is the equation of the perpendicular bisector of chord AB?

• y = 2x + 4

• y = 2x + 6

• y = -2x + 6

• y = 2x - 6
