Question

A jetski rental company charges a $50 deposit, plus $25 per hour to rent a jetski. This can be represented by the formula T = 25h + 50, where T is the total cost, and h is the number of hours rented. What would change the y-intercept of the equation?

Answer 1

Increasing/Decreasing the initial deposit would change the y-intercept. 

Answer 2

In order to change the y-intercept of the equation.

The charge of the deposit must be changed.

Explanation:

A jetski rental company charges a $50 deposit, plus $25 per hour to rent a jetski.

This can be represented by the formula by:

T = 25h + 50 ,

where T is the total cost, and h is the number of hours rented.

The condition or the situation that would change the y-intercept of the equation is when we change the charge of a deposit.

Since, this deposit is a fixed amount that is to be paid to rent a jetski.

Later on the extra charge is charged based on the number of hours rented.
