Answer:

-\dfrac{2}{3}

Step-by-step explanation:

When variable y is said to be proportional to another variable x, it is written as:

y \propto x

To introduce the equality sign, we introduce what is called the constant of proportionality, say k and write the above as:

y=kx

Comparing the given equation:

y=-\frac{2}{3}x

We can see that our constant of proportionality:

k=-\dfrac{2}{3}
