3)  I can use an equation to describe data in a scatter plot, and I can relate the parts of that equation to the story of the data. 

The peach delivery truck's cargo is approximated by the equation: t = 40000 - 2000d, 

with t as the weight of peaches in the truck and d as the number of deliveries made.

What do the parts of the equation mean about the truck?

Does the equation match data from the company?
