Which one of these relationships is different than the other three? Explain how you know. Hint: Find all of the constants of proportionality.

Graph 2 has a different constant of proportionality

Step-by-step explanation:

See attachment for graphs

To calculate the constant of proportionality, we simply determine the slope of each graph using

Where x's and y's are corresponding values of x and y

Graph 1:

Substitute these values in:

Graph 2:

Substitute these values in:

Graph 3:

Substitute these values in:

Graph 4:

Substitute these values in:

From the calculations above, graph 2 has a different constant of proportionality of 5.5 while others have 5 as their constant of proportionality
