Answer:

(-3, 1) and (2, -1)

Step-by-step explanation:

We'll just substitute in these coordinates.

First Pair:

2(-3) + 5(1) = -1

-6 + 5 = -1

-1 = -1

This works!

Second Pair:

2(5) + 5(-3) = -1

10 - 15 = -1

-5 ≠ -1

This does not work.

Third Pair:

2(2) + 5(-1) = -1

4 - 5  = -1

-1 = -1

This also works!

Fourth Pair:

2(-4) + 5(2) = -1

-8 + 10 = -1

2 ≠ -1

This does not work.
