Question

What is the constant of proportionality in the equation y=\dfrac{5}{9}xy= 9 5 ​ xy, equals, start fraction, 5, divided by, 9, end fraction, x? constant of proportionality ==equals

Answer 1

Answer:

5/9

Step-by-step explanation:

If a variable y is directly proportional to x, then;

y = kx where;

k is the constant of proportionality

Given the expression y = 5/9 x

On comparing with the general formula;

kx = 5/9 x

k = 5/9

Hence the constant of proportionality of the expression is 5/9
