Distance Midpoint Slope Parallel and Perpendicular

What is the distance between the two points?

• √40 ≈ 6.32

• √32 ≈ 5.66

• √20 ≈ 4.47

• none of these

Find the slope of the line through each pair of points.
(20,8), (9,16)

• -16

• -11/8

• 8/11

• -8/11

Find the slope of the line through each pair of points.
(1,-19), (-2,-7)

• 26/1

• 9/4

• -4

• -1/4

Find the distance.

• √95

• √115

• √136

• √162

Find the midpoint of the segment with the endpoints:
(6, 7) and (6, -5) 

• (0, -1)

• (6, 1)

• (1, 6)

• (0, 1)

Find the midpoint of the segment with the endpoints: 
(-4, 5) and (7, -9) 

• (-1.5, 2)

• (5.5, -7)

• (-2, 1.5)

• (1.5, -2)

What will the same slopes tell you about the quadrilateral?

• Opposite sides are parallel

• Opposite sides are congruent

• Diagonals are congruent

• Diagonals bisect each other

How do you show the diagonals are congruent?

• Measure them with a ruler

• Use the midpoint formula

• Use the slope formula

• Use the distance formula

How do you show diagonals are perpendicular?

• They would have opposite reciprocal slopes

• They would have the same slope

• They would have the same midpoint

• They would look perpendicular

How do you show diagonals bisect each other?

• Use the distance formula-they would have the same length

• Use the midpoint formula-they would be the same

• Use the slope formula-they would have opposite reciprocal slopes

• Hope I don't have to show this on the test
