Question

The ordered pair below is a solution to which equation? (2, 12) A. y = 6x B. y=1/2x C. y = 2x D. y=1/6x

Answer 1

We can substitute the values of x and y to see which equation is satisfied.

A. 12 = 6(2) 
12 = 12, true

B. 12 = 1/2 (2)
12 ≠ 1, false

C. 12 = 2(2)
12 ≠ 4, false

D. 12 = 1/6 (2)
12 ≠ 1/3, false

The answer is A.

Answer 2

Substitute the x for 2 and the y for 12 in each equation. The first choice works out. (12)=6(2), 12=12. This means the answer is true. A is your answer.
