Answer explanation

The correct choice is that y=\frac{1}{2}x is LESS STEEP than y=x because the slope of y=\frac{1}{2}x is smaller than the slope of y=x.

Brendan and his family are going to rent bicycles while they are on vacation. The costs to rent bicycles from two different companies are shown below. What is the cost to rent bicycles for 8 days from each company?

The Bicycle Company cost can be found using the function y = 15x + 10

The cost for Island Bike Rentals is shown in the table.

Hint: You need to find the rate of change and y-intercept for the table to write the function for Island Bike Rentals.

• The Bicycle Company would cost $120 and Island Bike Rentals would be $160

• The Bicycle Company would cost $130 and Island Bike Rentals would be $160

• The Bicycle Company would cost $120 and Island Bike Rentals would be $80
