Formula to tell if a point would fall above or below a line in a graph.

Below is the chart. The numbers that decide where the point plots from are the PI ('T-89 & T-90'!I10) and LL ('T-89 & T-90'!I8)

Hi

If I understand correctly you already have the equation of the line in the chart image you posted, pi=0.73(ll-20)??

 

[jondavis1987]

Yes, that is the equation of the line. I need an IF formula that tells me if the cells listed above would create a point above that line. I would like to either generate "Yes" or "No". I'm not really sure how to translate the whole thing into the formula.

Never mind. I got it. Needed some coffee.
