Take notes about your classmates’ presentations of their graphs.

## Hint:

As your classmates present, ask questions such as:

- What does each variable and number in the formula for the stack of cups represent?
- What does each variable and number in the formula for the stack of books represent?
- How are the two formulas similar? How are they different?
- Can you explain how you made your table?
- How did you use your table to make your graph?
- How do your predictions from the beginning of the lesson compare to your findings?
- What do you know about the table of values that define a proportional relationship?
- What do you know about the graph of a proportional relationship?
- When does the graph of a straight line not define a proportional relationship?
