Default weighted trendline

Can you scan a page or two of a textbook that explains this weighting
(hopefully with example) and send files to my private email (remove
TRUENORTH. or visit website to get my real email address)
best wishes

Can anyone tell me if it possible to weight a linear trendline in excel?
Like a calibration line where you can weight by 1/x where x is the
variance
at each point on the line.
