By asking if it's a "solution" they want to know if the coordinate makes the statement true. So you plug in the points for each one, solve, and see if the answer is a correct statement. If so, it's a solution. If not, then it's not a solution.

For instance, if you had the equation y < 2x + 3...

And my point is (0,4), plug in and work:

4 < 2(0) + 3

4 < 0 + 3

4 < 3

This is an incorrect statement because 4 is not less than 3, so that's not a solution.

But if your point is (1,4), plug in:

4 < 2(1) + 3

4 < 2 + 3

4 < 5

This is a correct statement because 4 is indeed less than 5, so that is a solution to that inequality.

You work them all this way. Go ahead and try it. :-)
