Work Step by Step

In order to find the loss in value that occurred during the second year, we must find the y-coordinates corresponding to x=1 and x=2 years. Looking at the graph, y=6.5 when x=1 and y=6 when x=2, where y is measured in thousands of dollars. We can subtract the y-coordinate when x=2 from the y-coordinate when x=1 to calculate the depreciation during the second year. $6.5-6.0=0.5$ Therefore, the copy machine lost $500 in value during the second year.
