Inverse Proportion

Inverse Proportion is where one value increase at the same rate as another decreases. In terms of direct proportion, y will be directly proportional to 1/x.

$$y = \frac{k}{x}$$

Where:

• k is the constant of proportionality

Example

It will take 2 days to write that documentation myself

Or will it? Bring in another developer working at the same rate and you'll have it done in a day. A fourth developer? Half a day.

$$\begin{align} y & = \frac{k}{x} \\ total\;days & = \frac{2}{developer\;count} \end{align}$$
