A. The graph goes through the origin (0, 0): This statement is true. The equation passes through the origin because when x=0, y=0.

B. The graph is proportional: This statement is true.

To determine the graph is proportional or not, we need to calculate the average rate of change.

Data points available on the graph:(0, 0) (1, 2)(3, 6)(10, 20)

Rate of change =

Between (0, 0) and (1, 2):

Rate of change =
