Which of the following equations is an example of inverse variation between the variables x and y? a.y=x+6

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.
