Identifying Key Features of Linear Functions

What is the y-intercept?

• (6, 0)

• (0, 6)

• (-3, 0)

• (0, -3)

What is the y-intercept and what does it mean for 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
