Answer 1

I'll show you how you can test the ordered pair (-5, -6) which is NOT one of your choices. Then you can use the same technique for your choices.

Is (-5, -6) a solution of the equation 5x + y = -23?
Plug in -5 for x and -6 for y in the equation:
5(-5) + (-6) = -23
-25 - 6 = -23
-31 = -23
This is a false statement, so (-5, -6) is not a solution. If you get a true statement, then the ordered pair is a solution.
