Question

Which ordered pair is a solution to the equation 2x - 4y = 18? A. (-1, 4) B. (0, 4) C. (9, 2) D. (11, 1)

Answer 1

D (11, 1)

Explanation:

How you figure this out is you take the points and plug them into the solution.

So you have 2x-4y=18. The first number in the parenthesis is the x and the second number is y.

So if you plug in the numbers of letter D into the equation it is 2(11)-4(1)=18.

Then solve: 22-4=18.

18=18. D is your answer.
