Which of the following equations is an example of inverse variation between the variables x and y?

For this case we have that by definition, a direct variation is given by:

Where:

k: It is the constant of proportionality of the variables.

On the other hand, we have that the inverse variation is given by:

Where:

k: It is the constant of proportionality of the variables.

In this way, the correct option is:

Option A

Option A

Step-by-step explanation:

It is said that two variables x and y vary inversely if the increase of one of the variables causes the other to decrease.

This is represented by the following equation

Where k is known as variation constant

To answer this question, identify among the options given that the form has

The answer is the option A. with k = 9
