answer should be written as an ordered pair.

2.-9x - y = 29 and 9x +y= -29
Part B: Solve each system by graphing. Your final answer should be labeled clearly.
Show all work
1. x + 3y = -12 and 4x - 3y = -3

4.5 x 10 = 45

4.5 x 2 = 9

9 + 45 = 54

54 + 4.5 = 58.5

1 + 2 + 10 = 13 weeks

13.5 weeks = 3 months

2 months and 4 weeks
