Answer:
The answer is C because both ordered pair when they are substituted into the equation, both sides equal to each other.
Explanation:
All you do is substitute. (x,y)
A:
Substitute
11 = 8(1) + 3
Multiply the inside parentheses by the outside number
11 = 8 + 3
Add them together to get the solution.
11 = 11
Both sides equal to each other so that means that it is a solution to the equation.
B:
Substitute
-5 = 8(-1) + 3
Multiply the inside parentheses by the outside number
-5 = -8 + 3
Add them together to get the solution.
-5 = -5
Both sides equal to each other so that means that it is also a solution to the equation.
D:
Both ordered pair gives you an equal solution to both sides.
