3.

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

Asemmisa {{asɛmmisaAhyɛnsode}}

4.

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!)
