Question

Is `y =4.2/x` a direct variation equation and if so, what is the constant of variation?

Answer 1

`"inverse variation"`

Explanation:

`"the standard form of a direct variation equation is"`

`•color(white)(x)y=kxlarrcolor(blue)"k is the constant of variation"`

`"the standard form of an inverse variation equation is"`

`•color(white)(x)y=k/xlarrcolor(blue)"k is the constant of variation"`

`rArry=4.2/x" represents inverse variation"`

`"with "k=4.2`
