so,

With x = -3 and y = -6 we have:

=> k = 18

Then,

#### Explanation:

This sounds like inverse proportionality.

The standard writing for such a formula is:

Given the information, y = -6 when x =-3, we can find the constant "k".

Now we know "k", we write the formula that sitifies y = -6 when x = -3 as
