The second graph is correct
A and B
Both A and B, when simplified get -(1/6), because the others have either 0 or 2 negative signs, denoting a positive end result.
X + y = -2
-x -x
y= -2 -x
2x -3y = -9
2x -3(-2 -x) = -9
2x +6 +3x = -9
-6 -6
5x = -15
5x/5 = -15/5
x= -3
y= -2 -x
y= -2 -(-3)
y= -2 +3
y= 1
the answer: (-3,1)
Answer:
