Answer:
(C)9/2
Step-by-step explanation:
Given the equation
[tex]\dfrac{x}{y}= \dfrac{2}{9}[/tex]
Two variables are in direct proportion when it is written in the form y=kx where k is the proportionality constant. To obtain the constant of proportionality, we simply make y the subject of the equation.
Therefore, we cross multiply.
2y=9x
Divide both sides by 2
[tex]y= \dfrac{9}{2}x[/tex]
Therefore, the constant of proportionality in the equation is 9/2.
Answer: Theoretically the answer will be (C)-9/2 If im wrong let me know
