The graph below represents the number
of containers and liters of water contained
in the containers. What is the constant of
proportionality?

Step-by-step explanation:

The picture of the question in the attached figure

we know that

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

Let

x ---> the number  of containers

y ---> liters of water contained  in the containers

Find the constant of proportionality k

From the graph take the point (2,20)

substitute

The equation is equal to

i think asking google will you get the answer to that question
