Does the graph represent a proportional relationship? Why or why not? Justify your answer.

As an AI language model, I cannot see the graph you are referring to. However, I can generally say that a proportional relationship exists between two quantities when they can be expressed in the form y = kx, where k is a constant called the constant of proportionality.

If the graph of two quantities is a straight line that passes through the origin (0,0), then the relationship between them is proportional. This is because the slope of a line passing through the origin is the same as the constant of proportionality (k) in the equation y = kx.

On the other hand, if the graph is not a straight line passing through the origin, then the relationship between the two quantities is not proportional.

Therefore, if you could provide me with the graph you are referring to, I can give you a more specific answer.
