Answer:

(-1, 3)

Step-by-step explanation:

The given equation is 2x + y = 5.

Test whether (-1, 3) is a solution. To do this, substitute -1 for x and 3 for y. Does 2(-1) + 3 = 5? No, it does not. So this could be the correct answer choice.

Test whether (6, -7) is a solution. Is 2(6) - 7 = 5 true? Yes, it is. So this is not a correct choice.

Test whether (3, -1) is a solution. Is 2(3) -1 = 5? Yes, it is. So this is not a correct choice.

Summary: The only answer choice that does NOT satisfy the given equation is the first one: (-1, 3).
