What is a constant of proportionality in the equation 3y equals 2x?
_/_

The constant of proportionality is

A relation between two variables, and , represent a proportional variation if it can be expressed in the form  

We have given that

Solve for y,

Remember that  the constant of proportionality is equal to the gradient of the line.

Therefore, the gradient of the line is

Therefore , the constant of proportionality is

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In this problem we have

Isolate the variable y

Divide by 3 both sides

Remember that

In a proportional relationship the constant of proportionality k is equal to the slope m of the line

The slope of the line m is

therefore

The constant of proportionality k is

5y
