Answer 2

We have been given an equation
`(x)/(y)=(2)/(9)`. We are asked to find constant of proportionality from our given equation.

We know that two directly proportional equations are in form
`y=kx`,where y is directly proportional to x and k is constant of proportionality.

Let us rewrite our given equation by cross multiplying as:

`2y=9x`

Now we will divide both sides of equation by 2.

`(2y)/(2)=(9x)/(2)`

`y=(9)/(2)x`

We can see that our equation is in form
`y=kx` and constant of proportionality is
`(9)/(2)`.
