The graph shows the percentage of Americans who moved in selected years.







a.) If the ordered pair $(x,y)$ represents a point on the graph, what does $x$ represent? What does $y$ represent?

The $x$-coordinates represent the year while the $y$-coordinates represent the percentage of Americans who moved in selected years.

b.) Estimate the percentage of Americans who moved in 2008.

Based from the graph, the estimated percentage of Americans who moved in 2008 was $12 \%$.

c.) Write an ordered pair $(x,y)$ that gives the approximate percentage of Americans who moved in 2008.

$(2008,12)$

d.) What does the ordered pair $(1951,21)$ mean in the context of this graph?

The ordered pair $(1951,21)$ shows that $21 \%$ of Americans moved in the year 1951.
