Question

Which relationship shows an inverse variation?

Answer 1

is it multiple choice or written response?

Answer 2

2 gif

Answer 3

The answer is D. When x increases, y decreases. That's an Inverse Variation.

C is like that too, but you have to multiply x and y and if you get the same answer, it's an Inverse Variation:

C:
(1, 4)
(2, 3)
(3, 2)
(4, 1)

1 x 4 = 4
2 x 3 = 6

4 and 6 are NOT the same.

D:
(2, 12)
(4, 6)
(6, 4)
(8, 3)

2 x 12 = 24
4 x 6 = 24
6 x 4 = 24
8 x 3 = 24

D is the correct answer.
