11. Which of these graphs represents a proportional relationship and why?


if you actually did all of them im giving you a hug.

Answer 1

Answers:

1. Miles driven

2. Price of rental

3. y = 2x + 6

(The fixed/initial cost is b, the y-intercept. The 2 is the price per mile and the x is the miles driven.)

4. y = 3x

(Since there's no initial cost, the equation is simply 3 times x)

5. A

6. The slope for Laguna is 2. This is the price per mile.

7. The slope for Salvatori is 3. This is the price per mile.

8. The y-intercept for Laguna is 6. This is the initial, fixed cost of renting a truck.

9. The y-intercept for Salvatori is 0. This means there is no initial cost.

10. The point of intersection is the amount of miles driven at which both companies are the same price. If Jenny drives 6 miles, she'll pay $18 either way.

11. I don't know how to do this one, sorry! >_<

I hope I helped on 1-10!
