Determine the constant of proportionality within a mathematical or real-world context given a table, graph or written description of a proportional relationship.

*Example:* Gina works as a babysitter and earns $9 per hour. She can only work 6 hours this week. Gina wants to know how much money she will make. Gina can use the equation e=9h, where e is the amount of money earned, h is the number of hours worked and 9 is the constant of proportionality.
