Thank you for the reply. I am looking at the trend line formula on the chart and it says:

Y=-12.5x+2466.7
R2 = 0.0242

To clarify this equation, If i say that the points move down every 12.5, the next value on the line will be 2466.7, and the closer R2 is to 1.0 the more accurate the trendline, am I correct?
