Question

Which equation represents inverse variation between x and y?

Answer 1

Inverse variation means

When the value of x increases the value of y decreases.

When the value of x decreases the value of y increases.

So for an inverse variation we have the expression

`y=(k)/(x)`

or

`x=(k)/(y)`

The expression which represents this condition is

`x=-(15z)/(y)`

Hence option b) or the second option is the right answer.
