Step-by-step explanation:

I take it you're looking for an explanation of the steps you've gotta take, so here's my best shot:

What you first have to do is figure out which set of coordinates goes with which equation. You can do this pretty easily with a calculator, by plugging in the first number in each coordinate to the equation and seeing if you get the second. For example, set 1 is (1, 5) and (2, 7). Putting 1 into equation IS would give you y=2/3(1)+3, which would have to equal 5 for it to be true, and you'd need to do the same process again with (2, 7). If both end up being true, note down which number went with which letters. When you've done them all, write down the letters in the corresponding boxes at the bottom (for instance, if equation IS did go with set 1, you'd write I and S in the boxes labeled 1 at the bottom), which should form a word or phrase if done correctly. It'll probably be time-consuming, but not too bad - I hope this helps! I can add another answer giving a step-by-step example if you're still unclear.
