Question

Which of the following represents inverse variation?

y equals nine divided by x

y equals three plus x

y divided by x equals negative ten

y equals negative one-sixth x

Answer 1

I think that it is A or C I am not sure

Answer 2

Inverse variation means as x in creases, y decreases by the same factor. So your x needs to be in the denominator since a bigger denominator means that y would be getting smaller. so \[y = \frac{9}{x}\] would be correct.
