MyCar Rental charges $15 per day to rent one of its cars plus an $8 service charge. 18 a. Write an equation that gives the total cost, y, for the number of days, x, that a car is rented. Equation:
(Ensure it is in slope-intercept form, y=mx+b.)

State the slope and the y-intercept of the line that your equation
represents.

y=15x+8

Step-by-step explanation:

$15 is PER day which means it has the x and the $8 is a one time charge for service.

Step-by-step explanation:

You should know what two-variable linear equations are. Specifically, you should know that the graph of such equations is a line. If this is new to you, check out our intro to two-variable equations(Opens in a new window).

You should also be familiar with the following properties of linear equations: y-intercept and xxx-intercept and slope.
