Question

What is the constant of proportionality in the equation y=2/3x?

Answer 1

2/3 is the proportionality constant in the given equation

Answer 2

The constant of proportionality in the equation is $\frac{2}{3}$

Solution:

Given that,

We have to find the constant of proportionality in the equation y = 2/3x

Given equation is:

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

We know that, when y is directly proportional with x, then

$y \propto x \\\\y = kx$

Where, "k" is the constant of proportionality

Compare the given equation with above eqn

$y = \frac{2}{3}x \\\\y = kx$

Thus,

$k = \frac{2}{3}$

Thus the constant of proportionality in the equation is $\frac{2}{3}$
