Molodets [167]

Answer:

$k=\dfrac{5}{9}$

Step-by-step explanation:

The given equation is :

$y=\dfrac{5}{9}x$ ...(1)

We need to find the constant of proportionality in the equation.

In this equation, y is directly proportional to x i.e.

y ∝ x

y = kx ...(2)

k is constant of proportionality

If we compare equation (1) and (2), we find that,

$k=\dfrac{5}{9}$

So, the constant of proportionality is equal to $\dfrac{5}{9}$ .
