(2;3) and (5;9)

• 2

• -3

• 8

• -1

Find the slope of the line.

Fill in the blank.

Decide whether the line with the given slope rises.

• m=2

• m=0

• m=-3

• m=1.5

• m is undifined

Find the slope and y-intercept of the line.
 $y=3x+1$  

• m=1, b=3

• m=-1, b=3

• m=-3, b=1

Each time you get dimes or quarters for change, you throw them into a jar. You are hoping to save $50. Write a model that shows the different numbers of dimes and quarters that you could accumulate to reach your goal.

• 0.10d + 0.25q = 50

• 0.25d + 0.10q = 50

• 0.10d - 0.25q = 50

• 0.10q + 0.25d = 150

Write an equation of the line that passes through the given point and has the given slope.

(-3;-7) and m=2

• $y=-7x-3$

• $y=-3x-7$

• $y=x-2$

• $y=2x-1$

Write an equation of the line.

Fill in the blank as y=mx+b, without any space.
