Constant Rate of Change

Match the equation to the graph

• y = -3 x -2

• y = 3 x +2

• y = 2 x +3

• y = -3 x +2

Match the equation to the graph

• y = 1/2 x - 4

• y = - 1/2 x + 4

• y = 1/2 x + 4

• y = 4 x + 1/2

In New York, the temperature was 40 degrees. The temperature continued to fall at a rate of 1.5 degrees each hour. Which equation can by used to find y, the temperature after x hours?

• y = 1.5 x + 40

• y = - 1.5 x + 40

• y = 40x - 1.50

• y = 40x + 1.5

Adrianna has $20 in her savings account. Each week she will add $5 to it. Which equation can be used to find y, the total amount of money in Adrianna's account after x weeks?

• y = 20 x + 5

• y = 5 x + 20

• y = 20 x - 5

• y = 5x - 20
