Question

Is `-3x=2y=0` a direct variation equation and if so what is the constant?

Answer 1

`k=-3/2`

Explanation:

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

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

`"rearrange "2y=-3x" into this form"`

`"divide both sides by 2"`

`(cancel(2) y)/cancel(2)=-3/2x`

`rArry=-3/2xtok=-3/2`
