Question

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

Answer 1

yes; `k = 3/2`

Explanation:

Direct variation model (a) passes through the origin and (b) x and y increase or decrease at the same rate. Constant of variation is the slope of the linear equation, so rewriting equation as `y= 3/2 x`, `k=3/2`
