#### Work Step by Step

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.
