Is the following equation below an inverse, direct, or neither variation?

Question

y=5/(x-8)

Answer 1

An inverse variation is of the form y = k/x

As the value of x gets larger, the value of y gets smaller

As the value of x gets smaller, the value of y gets larger

 

The same is true of y = 5/(x-8)

 

This is an inverse variation

Answer 2

A direct variation is in the form: y = kx

An inverse variation is in the form yx = k

 

What is given is in neither form. It is neither type of variation.

Answer 3

If y = 5/(x-8), then y varies inversely as x-8.

 

You cannot say, however, that y varies inversely as x.
