Between 1/2004 and 1/2006, the graph goes from a little above 5% to a little below 5%, so the change in unemployment rate is approximately -0.5 percentage points. The horizontal distance between these two points is 2 years. Therefore, the slope is approximately -0.5/2 = -0.25 or -1/4 which is closest to -1/2 choice C.
