Answer

$500

Work Step by Step

In order to find the loss in value that occurred during the first year, we must find the y-coordinates corresponding to x=0 and x=1 year. Looking at the graph, y=7 when x=0 and y=6.5 when x=1, where y is measured in thousands of dollars. We can subtract the y-coordinate when x=1 from the y-coordinate when x=0 to calculate the depreciation during the first year. $7-6.5=0.5$ Therefore, the copy machine lost $500 in value during the first year.
