How do I do this?
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.
