Answer:
The correct answer is D because both ordered pair when substituted to the equation, both sides of the equation didn't equal to each other.
Explanation:
All you do is substitute. (x,y)
A:
Substitute
7(1) - 2(5) = -5
Multiply the number inside the parentheses by the number outside.
7 - 10 = -5
Subtract the numbers.
-3 = -5
This is not the solution to the equation because the numbers on both sides don't equal to each other.
B:
Substitute
7(-1) - 2(1) = -5
Multiply the number inside the parentheses by the number outside.
-7 - 2 = -5
Subtract the numbers.
-9 = -5
This also not the solution to the equation because the numbers on both sides don't equal to each other.
C:
They both are not the solution to the equation because the numbers on both sides don't equal.
