When given an inverse variation, how do you find k?

atroni [7]

Considering an inverse proportional relationship, you find k taking a point (x,y), and multiplying the values of x and y.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

For an inverse relationship, the function is:

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

Then:

k = xy.

Which means that to find k, you take a point (x,y), and multiply the values of x and y.
