1. How do you use a graph to build and use a rule?

2. How do you use a graph to build and use a rule (dry)?

3. XY Y = X +

4. XY 0

5. XY 0-10 Y = X +

6. XY 0-10 Y = X +

7. XY 0-10 20 Y = X +

8. XY 0-10 20-30 Y = X +

9. XY 0-10 20-30 + 42 – 20 20 -20 m Y = X + + 20 m: -1

10. XY 0-10 20-30 + 42 – 20 20 -20 m Y = -1X + + 20 m: -1 b: -10

11. XY 0-10 20-30 + 42 – 20 20 -20 m Y = -1X + -10 + 20 m: -1 b: -10

12. Y = -1X + -10 (458, ?) X Y = -1(458) + -10 Y = -458 + -10 Y = -468

13. Y = X +

14. m: 5 b: -300 Y = X +

15. m: 5 b: -300 Y = 5 X + -300

16. (?, 485) Y 485 = 5X + -300 + 300 785 = 5X 55 157 = X
