HW: Introducing Proportional Relationships (Week 7)

1

Which table correctly shows the proportional relationship between the number of hours Kenny works and how much he earns?

1

How did you decide which table fits the relationship?

1

What is the constant of proportionality, or unit rate, for this relationship?

1

Using the form y = k * x, write an equation showing the relationship between the number of hours Kenny works and the amount he earns. (remember - k is the unit rate or constant of proportionality!)
