Question

The line models the cost of renting a bike. It costs ​$3 per hour plus a ​$1 deposit. Write an equation in​ slope-intercept form for the line where x is the number of hours a bike is rented and y is the total cost of renting a bike. How much does it cost to rent a bike for 4 ​hours?

Answer 1

The equation of the line is y = 1 + 3x and the total cost for 4 hours is $13

The equation of the line in slope--intercept form

From the question, we have the following parameters

Cost per hour = $3

Deposit = $1

The equation in​ slope-intercept form for the line is represented as

y = Deposit + Cost per hour * x

Where x is the number of hours a bike is rented and y is the total cost of renting a bike.

Substitute the known values in the above equation

y = 1 + 3x

The cost for 4 hours

Here, we have

x = 4

Substitute x = 4 in y = 1 + 3x

y = 1 + 3 x 4

Evaluate

y = 13

Hence, the cost is $13
