In an earlier lesson, we saw this graph that shows the percentage of all garbage in the U. S. that was recycled between 1991 and 2013. 1) Sketch a linear function that models the change in the percentage of garbage that was recycled between 1991 and 1995. For which years is the model good at predicting the percentage of garbage that is produced? For which years is it not as good?

2) Pick another time period to model with a sketch of a linear function. For which years is the model good at making predictions? For which years is it not very good?
