a. $(2002, 2133)$ and $(2007, 3478)$ b. $269$ c. There's an increase of 269 million pounds of yogurt produced every year.
a. Let $x$ be the year. Let $y$ be millions of pounds of yogurt produced. $(2002, 2133)$ and $(2007, 3478)$. b. $\frac{3478-2133}{2007-2002}=\frac{1345}{5}=269$ c. The slope represents the change in the amount of yogurt produced every year. Therefore, there's an increase of 269 million pounds of yogurt produced every year.
