check the changes each year: 
+0.30 
+0.23 
+0.45 
-0.90 
+0.37 
+0.74 
+0.10 
-0.11 
-0.15 
-0.93 

even without doing a regression, it is clear that no straight line can model this set of data with any real accuracy. 

But, I guess you can always plug in the data using your regression calculator to find the line of "best" fit. (see attachment).
