6. Identify Repeated Reasoning Suppose a relationship is proportional and the point (4, 10) lies on the graph of the proportional relationship. Name another point, other than (0, 0), that lies on the graph of the line.

8. Find the Error Karl said the point (1, 1) represents the constant of proportionality for the graph shown. Find his error and correct it.

7. MP Make an Argument Determine if a he can have a constant rate and not be proportional. Write an argument to defend your response.

9. Create The graph of a proportional relationship is shown. Describe a real-wort situation that could be represented by the graph. Be sure to include the meaning of the constant of proportionality. ​
