This graph shows a proportional relationship. What is the constant of proportionality?

Enter your answer as a decimal in the box.

The constant of proportionality is 0.3

Step-by-step explanation:

» The graph shows a direct proportiinality.

» Therefore, input the constant;

» When x is 5, y is 1.5:

0.3

Step-by-step explanation:

On a graph, proportional relationships are straight lines that extend through the origin.  

Slope of a graph = constant of proportionality of the equation

Let (5, 1.5) =

Let (20, 6) =

Formula of a slope:

So as the slope = 0.3, the constant of proportionality = 0.3
