Question

Is `y=2x-9` a direct variation equation and if so, what is the constant of variation?

Answer 1

`"not direct variation"`

Explanation:

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

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

`y=2x-9" is not in this form"`

`"so is not a direct variation equation"`

Answer 2

`"not direct variation"`

Explanation:

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

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

`y=2x-9" is not in this form"`

`"so is not a direct variation equation"`
