All answers are in cordinate pairs. Example (1,2) No Spaces between each character.
In Exercises 13–20, solve the system of linear equations
by graphing. (See Example 2.)
13. y = -x + 7
y = x + 1
14. y = -x + 4
y = 2x - 8
15. y = 5x + 2
y = kx + 5
16. y = x - 4
y = -x + 11
18. 4x - 4y = 20
17. 9x + 3y = -3
2x - y = -4
y = -5
19. x - 4y = -4
- 3x – 4y = 12
20. 3y + 4x = 3
x + 3y = -6
