Your data is reasonably linear. Using Solver I got:


y=84.39266744*x - 75.1925884

Oh Wise Ones,

I took these values from a large matrix(660 values). I would like to find
the formula to eleminate the matrix for obvious reasons. I have chosen some
round numbers from one of the axis and wondered how I can derive a formula
from these values. I can measure for X, but I need to find a Y value.

X= (((C5-C4*0.997)/((C5-C6)-(C4/2.7))))

X= 3 digits
Y= 1 digits

X Y
1.100=16.0
1.200=26.2
1.300=35.5
1.400=44.2
1.500=52.2
1.600=59.8
1.700=66.8

Thanks,
Mike
