When there's an inverse variation between two variables x and y they are related by an equation like this one:
[tex]y=\frac{k}{x}[/tex]
Or:
[tex]xy=k[/tex]
By taking a look at the options you'll notice that the only one that displays a relation like those above is:
[tex]y=\frac{6}{x}[/tex]
Then the answer is option D.
