Find the slope of the line that passes through 
(-4, 7) and (-6, -4)

• 2/11
• -2/11
• 11/2
• -11/2

Write equation of the line containing (-3,4) and (-1,-2)

• y = -3x - 5
• y = -3x + 1
• y = -3x + 13
• y = 3x + 1

Slopes of perpendicular lines are...

• negative reciprocals
• opposites
• identical
• flipped

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
