Question

Is `3x = y` a direct variation equation and if so, what is the constant of variation?

Answer 1

`3x=y`
`implies y=3x`

Since increasing value of `x` increases the value of `y` and decreasing the value of `x` decreases the value of `y`.

Therefore, it is a direct variation and `3` is the constant of variation.

`implies yprop x`
