Which ordered pair is not a solution of y=-4x-9

Answer 1

There are infinitely many ordered pairs that are not solutions of y=-4x-9, but one example is (1, -5).

When we substitute x=1 and y=-5 into the equation y=-4x-9, we get:

-5 = -4(1) - 9
-5 = -4 - 9
-5 = -13

This is a false statement, so (1, -5) is not a solution of the equation y=-4x-9.
