Question

Is 2x+3y=0 a direct variation and if so, what is the constant?

Answer 1

`2x+3y=0` is a direct variation with a constant of `(-2/3)`

Explanation:

Assuming `y` is the dependent variable
we can re-write the given equation as
`color(white)("XXX")y =-2/3x`
So the constant of variation is `(-2/3)`
