Find the slope of the line

-3/2

Step-by-step explanation:

Slope is rise over run or y/x

If the slope is angled down as it is in the picture it will be negative.

Step-by-step explanation:

The given equation is

For this function to have an inverse, we must restrict the domain, say

We interchange x and y to get,

We now make y the subject to get;

We divide through by 16 to get;

We now take the square root of both sides to get;

Since  , the inverse function is
