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

<h3>The equation of the line in slope--intercept form</h3>

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

<h3>The cost for 4 hours</h3>

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
