1 answer:
Answer:

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 a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have

Isolate the variable y
subtract 2x both sides


Divide by 6 both sides

therefore
The constant of variation is equal to
