What is the constant of proportionality in the equation [tex]$\frac{x}{y}=\frac{2}{9}$[/tex]?

A. [tex]$\frac{2}{9}$[/tex]

B. 2

C. [tex][tex]$\frac{9}{2}$[/tex][/tex]

D. 9



Answer :

Certainly! Let’s find the constant of proportionality in the equation [tex]\(\frac{x}{y} = \frac{2}{9}\)[/tex].

An equation of the form [tex]\(\frac{x}{y} = \frac{2}{9}\)[/tex] represents a proportional relationship between [tex]\(x\)[/tex] and [tex]\(y\)[/tex]. In a proportional relationship, the ratio between two variables is constant.

To determine this constant of proportionality, observe the right-hand side of the equation, which is [tex]\(\frac{2}{9}\)[/tex].

Thus, the constant of proportionality in the equation [tex]\(\frac{x}{y} = \frac{2}{9}\)[/tex] is [tex]\(\frac{2}{9}\)[/tex].

The question provides multiple choices for the constant of proportionality:
- [tex]\(\frac{2}{9}\)[/tex]
- 2
- [tex]\(\frac{9}{2}\)[/tex]
- 9

Comparing these options to our derived constant of proportionality [tex]\(\frac{2}{9}\)[/tex], the correct answer is:

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