To fill in the blanks based on the graph, you would typically analyze the graph's slope and y-intercept to determine the appropriate responses. Assuming the graph represents a proportional relationship, here’s how you can fill in the blanks:
A. The constant of proportionality is 2.
B. Write an equation that represents this graph. y = 2x.
C. This is a proportional relationship because the y-intercept is (0, 0).
Please verify these responses with the actual graph you are referring to, as adjustments may be necessary based on the specific details of the graph.
