Answer:
[tex]\text{The proportionality constant is }\frac{2}{3}[/tex]
Step-by-step explanation:
we have to find the constant proportionality for
[tex]y=\frac{2}{3}x[/tex]
Given two variables x and y, y is directly proportional to x if there is a non-zero constant k such that
y ∝ x
⇒ y=kx → (1)
Here, k is known as constant proportionality.
Now, [tex]y=\frac{2}{3}x[/tex] → (2)
Comparing (1) and (2), we get
[tex]k=\frac{2}{3}[/tex]
[tex]\text{The proportionality constant is }\frac{2}{3}[/tex]
