It costs $32 per day to rent a medium-sized car, plus $0.25 for each mile driven over 150 miles. The equation that

represents this situation is y = 0.25x + 32, where y represents the total cost of renting a car,

and x represents the number of miles driven over 150 miles.

Look at the graph of y = 0.25x + 32 that is shown above and answer the related questions.

1. Which variable in the equation is the independent variable and what represents the independent variable in this situation?

2. Which variable in the equation is the dependent variable and what represents the dependent variable in this situation?

3. What is the slope and what does the slope represent in this situation?

4. What is the y-intercept and what does the y-intercept represent in this situation?
