The graph describes US inflation between the years 1978 and 2010. It records college tuition 
and fees, educational books and supplies, house prices, consumer prices, and the average hourly 
wage. All five have a steady, matched up record until about 1985, where there's a bit of a

rise and fall between 2006 and 2008, while consumer prices and average hourly income remain 
the lowest of the five lines, never rising above 400
