The equation is given to be:

To check if the ordered pair satisfies the equation, we need to substitute the values into the equation. If it yields a mathematically true solution, then the pair satisfies the equation.
The ordered pair is (5, -4).
Make the following substitution:

Substituting, we have:

Since the mathematical expression is true, then this satisfies the equation and the ordered pair is a solution to the equation.
The correct option is YES.
