Can you give use two seperate equations (one for each line) of y=ax + b or equivalent. that will give us the actual slope of each. also i would like an r2 for both lines (if you have enough data). this doesnt retract from what EB said. 30 year periods really cant be justified for this stuff. if you plot the 30 years prior to and including 1999 what do you get?
