Strategic Advice: Your only choice for this question is to compare each statement to the graph. Cross out false statements as you go. Stop when you find a true statement.

Getting to the Answer: A graph is decreasing when the slope is negative; it is increasing when the slope is positive. Eliminate A because there are some segments on the graph that have a positive slope. Eliminate B because the slope is negative, not positive, between 2009 and 2010. Choice (C) is correct because the slope is negative for each segment between 2004 and 2007 and also between 2009 and 2011.
