What is the constant of proportionality in the equation StartFraction x over y EndFraction = StartFraction 2 over 9 EndFraction?

StartFraction 2 over 9 EndFraction

2

StartFraction 9 over 2 EndFraction

9

(C)9/2

Step-by-step explanation:

Given the equation

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

Therefore, the constant of proportionality in the equation is 9/2.

it has the same slope and a different y-intercept

hope this : )
