Find the y-intercept(s) of the graph shown.

• (-3.3, 0)

• (5.6, 0)

• (-5, 0)

• (0, 4)

What is the y-intercept and what does it mean in the context of the problem?

• (0, 32). This means that the cost before renting the car is $32

• (10, 35). This means that at 10 miles driven, the cost is $35.

• (30,40). This means that the cost after 30 miles driven is $40

• (32, 0). This means that the cost before renting the car is $32

• B

• C

• D

The graph models a linear relationship between the number of monthly payments made on a loan and the remaining balance in dollars left to pay on the loan. Which statement describes the x-intercept of the graph?

• The x-intercept is 60, which represents the initial balance in dollars of the loan

• The x-intercept is 27,000, which represents the initial balance in dollars of the loan

• The x-intercept is 60, which represents the number of monthly payments needed to repay the loan

• The x-intercept is 27,000, which represents the number of monthly payments needed to repay the loan
