Solve a system by substitution: both equations in slope-intercept form

Use substitution or elimination so that you find x and y. Write your answer as (x, y).

1. Solve the system: y = −4x − 6 and y = −2x − 2. Write your answer as (x, y).
2. Solve the system: y = 4x − 6 and y = −3x + 15. Write your answer as (x, y).
3. Solve the system: y = 3x + 6 and y = −5x − 10. Write your answer as (x, y).
4. Solve the system: y = 3x + 7 and y = 4x + 9. Write your answer as (x, y).
5. Solve the system: y = −3x − 2 and y = −x − 4. Write your answer as (x, y).
6. Solve the system: y = −2x + 5 and y = 6x + 13. Write your answer as (x, y).
7. Solve the system: y = 2x + 18 and y = −6x − 22. Write your answer as (x, y).
8. Solve the system: y = 4x + 17 and y = 5x + 20. Write your answer as (x, y).
