x+4y=12

• Parallel
• Perpendicular
• Neither

These lines are....
y=2
x=11

• Parallel
• Perpendicular
• Neither

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
