Yes this graph is a function because the x and y values all have their own independent input and outputs therefore being a function. The domain and range are specific meaning it the graph corresponds to the values given on the graph. There are closed circles meaning the funciotn has value. If they were both open circles the function wouldn't have any value!
This is an insane assignment!! Hope that helps ya out!!

Answer: (4,6)
Explanation:
x - 3y = -14
x - y = -2
Multiply a -1 to the first equation so the x’s can cancel out.
-x + 3y = 14
x - y = -2
Subtract the two equations together.
2y = 12
y=6
Now, plug in y to one of the original equations.
x - (6) = -2
x=4
Therefore, the answer is: (4,6)
