Is the relationship shown in the table at right proportional? If so, use it to complete a Proportions Web. If not, explain why it is not. 

For the relationship to be proportional, there must be a steady rate at which dirt is excavated that begins with cubic
yards excavated after hours of work.

Yes, this relationship is proportional, since the amount of dirt excavated divided by the hours worked is a constant ratio.

 cubic yards per hour.

Now write the equation for this relationship and then graph it.

Amount of Dirt Excavated
(cubic yards)
