Question

What is the constant of proportionality in the equation y = 5/9x?

Answer 1

Equation for direct proportional function is

y = kx, where k is a constant of proportionality

so for   y=5/9 x

k=5/9.

Answer 2

Answer:

The constant of proportionality of the equation $y = \frac{5x}{9}$ is $k= \frac{5}{9}$ .

Step-by-step explanation:

Definition of constant of proportionality

Let us assume that x and y are two variables .

$y \propto x$

y = kx

Where k is the constant of proportionality .

As given the equation

$y = \frac{5x}{9}$

Compare this equation with y =kx .

Thus

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

Therefore the constant of proportionality of the equation $y = \frac{5x}{9}$ is $k= \frac{5}{9}$ .
