Question

The equation below describes a proportional relationship between x and y. What is the constant of​ proportionality? y= 2/9x

Answer 1

Answer:

$\frac{2}{9}$

Step-by-step explanation:

Constant of proportionality is defined as the ratio between two directly proportional quantities.

If suppose $x$ and $y$ are the two directly proportional quantities, then we can say that constant of proportionality is given as $\frac{y}{x}$.

Here in the question,

$y=\frac{2}{9}x$

Dividing both sides by $x$, we get

$\frac{y}{x}=\frac{2x}{9x}$

$\frac{y}{x}=\frac{2}{9}$

So, constant of proportionality is $\frac{2}{9}$.
