# How do you determine whether #y/x=9# is an inverse or direct variation?

To determine whether y/x=9 is an inverse or direct variation, we need to analyze the equation. In inverse variation, as one variable increases, the other variable decreases, and their product remains constant. In direct variation, as one variable increases, the other variable also increases, and their ratio remains constant.

In the given equation y/x=9, we can see that as x increases, y also increases, and their ratio remains constant at 9. Therefore, y/x=9 represents a direct variation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
