Take each ordered pair and see if it satisfies the equation.

I'll take the forst one, and you'll do the rest.

The first ordered pair is (-1,11).

Does -11 = -2(-1) + 9?
         -11 = 2 + 9?
           
-11 = 11?
   No.

So the first ordered pair does NOT work.

Now you check the other ordered pairs.
