which one is an inverse variation?

Question

y = x2

y = 7x

y = x3

y =7/x

Answer 1

Hi, Jonathan.

Inverse variation is expressed in this format:

y = k/x , where x and y are variables in the problem, and k is a [k]onstant value.

For example if weight varies inversely with temperature, you would write an equation like this to represent this scenario:  w = k/t

In your question posed above, there is only one choice that looks like what I've described.
