Question

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

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  $\frac{2}{9}$
