Answer:

[tex]\frac{2}{9}[/tex]

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 [tex]\frac{y}{x}[/tex]

Here in the question,

 [tex]y=\frac{2}{9} x[/tex]

Dividing both sides by x, we get

[tex]\frac{y}{x} =\frac{2x}{9x}[/tex]

[tex]\frac{y}{x} =\frac{2}{9}[/tex]

So, constant of proportionality is  [tex]\frac{2}{9}[/tex]

  • 2y=9x

I assume this is the equivalent equation as it contains x and y

If 2y=9 is actual one the. y=9/2 so no constant of proportionality

  • y=Kx
  • y=9/2x

Constant of proportionality 9/2
