  3. Proportionality We will look at tables, graphs, equations, and ordered pairs to determine if the relationship between the variables is proportional. YIP: Proportional Relationship: a relationship between TWO quantities where the RATIO remains constant. YIP: This constant ratio is called the “constant of proportionality” (UNIT RATE). The constant of proportionality can never be zero.

  4. Does the table show a proportional relationship between x and y? Explain.

  5. Proportional relationships and tables The table shows the costs for four different photocopying jobs. Is there a proportional relationship between the number of copies and the cost? How do you know?

  6. Proportional relationships and tables Does the table show a proportional relationship between the number of heartbeats and time? Explain.

  7. Proportional Relationships and Tables At a café, the cook uses a recipe that calls for eggs and milk. The amounts of eggs and milk have a proportional relationship. Complete the table.

  8. At HMS, there is an average of 26 students per teacher. Complete the table below to show the proportional relationship.
