with usage of the vehicle

vehicle operating costs that do not

vary from month to month

9. rebate

10. variable cost

the value of y when x = 0

11. function

Answer 1

1. Ordered pair- an expression written (domain term, range term)

2. range- terms on the vertical axis

3. slope- ratio of the vertical change to the horizontal change of a line

4. y-intercept- the value of y when x = 0

5. constant- element in an equation that does not change value

6. discount- lowers the price of a vehicle

7. fixed cost- vehicle operating costs that do not vary from month to month

8. independent variable- variable in an equation that can take have different values

9. rebate- returns part of the price

10. variable cost- vehicle operating costs that vary with usage of the vehicle

11. function: for any value in the domain there is one and only one value in the range

12. domain: terms on the horizontal axis

Hope this helps!!
