he graph shows the values I (in billions of dollars) of goods imported to the United States and the values E (in billions of dollars) of goods exported from the United States from 1980 through 2013. Approximate the average rates of change of I and E (in billions of dollars per year) during each period.† A scatter plot titled Trade Deficit has a horizontal axis labeled t = Year (0 ↔ 1980) with values from 0 to 35 and a vertical axis labeled Value of goods (in billions of dollars) with values from 0 to 2,400. There are two groups of points on the scatterplot. The group of points labeled I has 34 points. A pattern goes up and right becoming more steep from (0, 250) to (33, 2,300). The points are as follows.
