REFLECTION:
This problem is a great example of proportional relationship because it shows that the pay increase by the same amount with each passing hour, instead of increasing or decreasing by a disproptional amount.
This problem also demonstrates that the unit rate is the slope of the graph becauseit clearly shows that the unit rate is 10$/1 hour, and on the graph the amount of $ is directly proprtional to the amount of time.
The answer to #9 is NOT a unit rate because one value is not to a value of 1, like in the answer to question #6.
