Answer:
[tex]\frac{2}{3}[/tex].
Step-by-step explanation:
We have been given an equation [tex]y=\frac{2}{3}x[/tex]. We are asked to find the constant of proportionality.
We know that two directly proportional quantities are in form [tex]y=kx[/tex], where y is directly proportional to x and k is the constant of proportionality.
Upon looking at our given equation, we can see that [tex]k=\frac{2}{3}[/tex], therefore, the constant of proportionality is [tex]\frac{2}{3}[/tex] for our given equation.
