Question

In this graph, the number of containers is plotted along the x-axis and the amount of water in the containers is along the y-axis.




the proportionality constant of the graph (y to x) is

Answer 1

The proportionality constant is the slope of the line.
20/2 = 10

Answer 2

Answer:

10 liters/containers

Step-by-step explanation:

The line has a general equation of:

$(y-y_o)=k(x-x_o)$

where k is the proportionality constant and has the following equation

$k=\frac{y_1-y_o}{x_1-x_o}$

Let's take 2 points (0,0) and (2,20), then the proportionality constant is

$k=\frac{20-0}{2-0} =10 liters/containers$

The constant relates the average amount of water per container
