Answer:
3(2x-2)-4(x+7)+20 = -8 => x = 13
Step-by-step explanation:
3(2x-2)-4(x+7)+20 = -8
6x-6-(4x+28)+20 = -8
6x-6-4x-28-20 = -8
6x-4x-6-28 = -8
2x- 34 = -8
2x -34 +34 = -8 +34
2x = 26
x= 13
Y=80
X=30

Point A shows that she is incorrect.
With functions, you can perform the "straight line test through each point. If the line goes through both points, you know it's not a function.
If we plotted point A, it'd fail the straight line test because the given point (-6, 7) already has -6 as an x value.
