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.
Hope this helps!

Answer:
5(9x + 2y + 10)
or
x = 0
y = -5
Step-by-step explanation:
If you are just factoring this, you will factor a 5 out from everything.
5(9x + 2y + 10)
or if you are trying to solve just isolate one of the variables and then substitute it into the original equation
45x + 10y = 50
10y = 50 - 45x
y = 5 - 4.5x
45x + 10(5-4.5x) + 50
45x + 50 - 45x + 50
x=0
45(0) + 10y + 50
0 + 10y + 50
10y + 50
10y = -50
y = -5
and it would be x = 0 and y = -5
