The graph shows the distance a certain cyclist can travel at a constant speed with respect to time. Which of the following best describes the meaning of the slope of the line representing this situation?

• The cyclist travels at a speed of about 8 meters per second.

• The cyclist travels at a speed of about 2.5 meters per second.

• The cyclist travels at a speed of about 5 meters per second.

• The cyclist travels at a speed of about 10 meters per second.

Identify the scenario below that represents a proportional relationship.

• Autumn owes her mother $5 and earns $0.75 for each chore she completes.

• The art teacher charges a supply fee of $6.00 and $0.50 for every lost item.

• Hunter charges $3.00 for each candied apple at his fall festival booth.

• Colten lost $0.75 on the bus yesterday and earns $2.00 per chore.

Does the table show a proportional relationship?

• Yes, it is proportional because it has a constant slope.

• Yes, it is proportional because it passes through (0,0).

• No, it is not proportional because it does not have a constant slope.

• No, it is not proportional because it does not pass through (0,0).
