The cost of renting roller blades is $4 plus $3.50 for each hour that the roller blades are rented. write an expression to represent the cost in dollars of renting roller blades for h hours?

The expression is equal to

Step-by-step explanation:

Let

x ----> the number of hours that the roller blades are rented

y ----> the cost of renting roller blades in dollars

we know that

The linear equation in slope intercept form is equal to

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

The slope is equal to

The y-intercept is equal to

----> value of y when the value of x is equal to zero

substitute

For x=h hours

substitute

found it xd it ok yt
