You just need to plug in the numbers for x and y and see if the resulting equation is true. Remember in each ordered pair, the first number is the x value, and the second number is the y value.

For example with the first pair (2,-1) the equation becomes:

2 - 3*(-1) = -7.

Ask yourself: Is this equation true?

If so then  circle the pair (2,-1), otherwise leave it uncircled.

Then repeat this with each of the other three pairs.
