1. Cell phone expenditure increased consistently.
2. Residential phone expenditure decreased consistently.
3. The two lines crossed, with cell phone spending overtaking residential spending midway through the period.

Sample Overview: Overall, there was a significant divergence in spending patterns over the decade. While expenditure on cell phone services rose sharply, spending on residential phone services followed a continuous downward trend. Notably, cell phone expenditure surpassed residential phone expenditure around 2006.

Now, you need to describe the details. Group similar information together. A common approach is to dedicate one paragraph to each line, but you can also group by time periods. Make sure to use data to support your descriptions and make comparisons where relevant.

Body Paragraph 1 (Cell Phone Spending): In 2001, the average American spent just under $250 on cell phone services. This figure rose steadily over the following years, climbing to approximately $500 by 2005. The upward trend continued, and by 2010, expenditure on cell phones had reached a peak of nearly $750.

Body Paragraph 2 (Residential Phone Spending): In contrast, spending on residential phone services started at a much higher point, at just over $700 in 2001. However, this figure decreased consistently throughout the period. It fell to around $600 by 2004 and continued dropping to approximately $400 by 2010. The two lines intersected in 2006, after which cell phone expenditure remained higher for the rest of the decade.
