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.

What you will learn in this lesson

What is the slope-intercept form of two-variable linear equations

How to find the slope and the yyy-intercept of a line from its slope-intercept equation

How to find the equation of a line given its slope and yyy-intercept

What is slope-intercept form?

Slope-intercept is a specific form of linear equations. It has the following general structure.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
