fill in data range knowing start and end values
 

I am trying to extrapolate a payout curve. I know payouts start at a 95%
index. The payout at that level is 25%. A 100% index yields a 100% payout.
How do I determine the values in between? I know I have done this once
before. Since it has been about a year, I have forgotten how to do this.

wouldn't it be

=(100%-25%)/(100-95) = 15% per index point?
