Question Group #1
Directions and/or Common Information: Graph and determine the solution to each linear system.


x + y = 9          x + y = 3
1. 





2y - 3x = 12         2y - x = 8
2. 





y - x = -4          y + x = -4
3. 





y - 4x = 8          x + 2 = 0
4. 





-2x + 3y = -24          4x - 6y = 48
