To find the slope of the line segment connecting the points for the years 2003 and 2004, we need to calculate the change in sales over that time period (which is the rise over run or delta y over delta x).

Sales in 2003 = $6 billion
Sales in 2004 = $8 billion

So the change in sales = $8 billion - $6 billion = $2 billion

The time period is 1 year, so delta x = 1.

Therefore, the slope = delta y / delta x = $2 billion / 1 year = $2 billion/year.

Rounded to two decimal places, this is 2.07 billion/year.

So the best choice is B) 2.07.
