PLEASE PLEASE HELPPPPP!!!
Solve each problem by graphing. Determine if it is consistent or inconsistent.
1. x + y = 3, x – y = 0
2. 3x + 2y = 5, 6x + 4y = -3
3. x + y = 3, x + y = -2
4. x – y =0, 2x – y = 0 (0, 0)
5. x + 2y = 0, x + y = 1 (2, -1)
6. x – 4y = 9, 2x – 3y = 8 (1, -2)
7. 3x + 9y = 9, 2x – 3y = 6 (3, 0)
8. x + y = 2, x – y = 0 (1, 1 )
9. x + y = 1, x – y = -3 (-1, 2)
10. 2x + y =2, x -2y = -4 (0, 2)
11. 2x + 3y = 3, 4x + 6y = -12
12. 3x -2y = -1, 2x – 4y = 2
13. y = -1, x = -2
14. x – y = 1, y = 2
15. 3x + 3y = 21, 3x + 4y = 24
16. 3x + 2y = 5, 9x + 6y = 12
17. 2x + y = -6, x = -3
18. 4x + 9y = 13, y = x
