Answer:
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:
<em>From the calculations above, graph 2 has a different constant of proportionality of 5.5 while others have 5 as their constant of proportionality</em>
