Answer: third option
[tex]y = \frac{4}{x}[/tex]
Step-by-step explanation:
It is said that two variables X and Y vary inversely if when the variable x increases then the variable and decreases.
The equations of inverse variation have the following form:
[tex]y = \frac{k}{x}[/tex]
Where k is the constant of variation
To know which of the equations varies inversely identify those that have the form
[tex]y = \frac{k}{x}[/tex]
You can see that the correct option is the third option
[tex]y = \frac{4}{x}[/tex]
