Answer:

Nonrefundable deposit: y = 30x + 150

Refundable deposit: y = 30x

In both cases, the slope is 30.

Explanation:

The equation is:

y = 30x + 150

[Total Cost is equal to the rate per hour times the number of hours, plus the $150 deposit]

The slope is 30 [30x]

It doesn't say if the deposit will be refunded. If it is, then the total cost is: y = 30x.
