Question

8. Which set of ordered pairs satisfies an inverse variation?

F. (6, 3) and (8,4) G. (2, -3) and (4, 5)
H.(4, -2) and (-5, 10) J. (2, 6) and (-3,-4)

Answer 1

H.(4, -2) and (-5, 10)

Explanation:

We have pairs of point (x,y)

If y decreases as x increases, we have an inverse variation.

In this question:

F.

y increases by 1 when x increases by 2. So not inverse.

G

x increases by 8 when x inches by 2. So not inverse.

H

x goes from -5 to 4, y decreases from 10 to -2. So inverse and H is the answer.

J.

x goes grom -3 to 2, y from -4 to 6, both increase, so this is not the answer.
