What is the constant of proportionality in the equation 3y = 2x

2/3

Step-by-step explanation: recall that y varies directly with x

this gives y = kx.

where k is the constant of proportionality.

divide 3y = 2x by 3

this gives y = 2/3 x. the coefficient of x is 2/3 which is the constant.

k = 2/3

Step-by-step explanation:

When a variable y directly relates to another variable x, we can say:

y=kx

Given the equation, we can say

3y=2x

y = 2x/3

Putting the value of y from above discussion

kx = 2x/3

x is being cancelled on both sides of equation

k = 2/3
