In order to determine the constant of proportionality, we need to divide the quantities from the  coordinate by the quantities from the  coordinate. In order for the graph to show a direct proportion, each quotient should equal the same value. 

First, we need to find a series of coordinate points:

Now that we have a series of coordinate points, we can divide to find the constant of proportionality:

All of the quotients are the same value; therefore, this graph does show direct proportion and the constant of proportionality is .

In order to determine the constant of proportionality, we need to divide the quantities from the y-coordinate by the quantities from the x-coordinate. In order for the graph to show a direct proportion, each quotient should equal the same value. 

First, we need to find a series of coordinate points:

Now that we have a series of coordinate points, we can divide the y-coordinate of each by its corresponding x-coordinate to find the constant of proportionality:

For point (4, 1), 1 divided by 4 is 

For point (8, 2), 2 divided by 8 is 

For point (12, 3), 3 divided by 12 is 

All of the quotients are the same value; therefore, this graph does show direct proportion and the constant of proportionality is .
