Explain in your own words what two things must be true about a graph for it to show a proportional relationship.
Imagine you are looking at a graph that shows the relationship between the number of hours someone works and the amount of money they earn. The graph is a straight line, but it starts at the point (0, 10) instead of (0, 0). Does this graph represent a proportional relationship? Why or why not?
