Distance, Midpoint, Slope, Parallel and Perpendicular

A second linear equation is graphed next to the equation y = 5x + 10. Which of the following could represent the slope and y-intercept of the line if the 2 lines are parallel?

• m = 10, y-int: (0, 5)

• m = 5, y-int: (0, 10)

• m = 5, y-int: (0, 4)

• m = 2, y-int: (0, 5)

What slope is parallel to:  
m = 3/4

• 4/3

• 3/4

• -3/4

• -4/3

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

What is the distance between the two points?

• √40 ≈ 6.32

• √32 ≈ 5.66

• √20 ≈ 4.47

• none of these

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
