Please help me answer this question?

Answer: It is a solution.
Step-by-step explanation:
First you should replace x and y with the x and y coordinates from the ordered pair. Now you should have 5(-2) - 2(-4) = -2. Now multiplyit out. You should now have -10 - (-8) = -2. Next, subtract. Since you are subtracting a negative, it acts like adding a positive. -10 + 8 = -2. Now add 8, and you should get -2 = -2. This is a solution.
