Select all ordered pairs that satisfy the function y=4x+3.

I suppose that you should have given some pairs to choose from.

Anyway, I can tell you how to do it. Given a pair , you have to substitute and to and respectively, and see if you get something true.

For example, the pair satisfies the function, because the substitution yields

which is true. On the other hand, the pair doesn't satisfy the function, because

is clearly false.
