5. C

6. A

Step-by-step explanation:

To find the answer, plug in the x- and y-values into each equation. When the equation comes to be true that is your answer.

So for question 5, you plug -5 into the x and 13 into the y for each equation. The first equation will give you an answer of 13 = -7, which isn't true.

The second will give you 13 = 7, so you keep going.

The third gives you 13 = 13, which is true, so that one must be the answer.

Do this for every question and it will give you the answer.
