Question

According to the line of best fit in the scatterplot above, which of the following best approximates the year in which the number of miles traveled by air passengers in Country $X$ was estimated to be $550$ billion?

• A. 1997
• B. 2000
• C. 2003
• D. 2008

Answer 1

The correct option is C 2003

The best fit line crosses the horizontal line passing through $550$ billion somewhere between $2000$ and $2010$.

Also, since its before the middle line, the year would lie in between $2000$ and $2005$.

The option which matches to that year is $2003$, and hence is the correct answer.
