# Assume that y varies inversely as x, how do you write an inverse variation equation that relates x and y given y=12 when x=-9?

The inverse variation equation that relates x and y given y=12 when x=-9 is y = k/x, where k is the constant of 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.
