# How do you write an inverse variation equation given y=-1 when x=-12?

The inverse variation equation can be written as y = k/x, where k is a constant. To find the value of k, substitute the given values of x and y into the equation and solve for k. In this case, when x = -12 and y = -1, the equation becomes -1 = k/(-12). Solving for k, we get k = 12. Therefore, the inverse variation equation is y = 12/x.

In an inverse variation - or inverse proportion, as one quantity increases the other decreases.

Variations (proportions) are linked by a constant (k)

We can write a variation as an equation by using the constant.

This is the equation for a hyperbola which is the graph of inverse proportion.

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.
