In  GOOGLE,  perform a search  " Calculate linear regression online ".

Google will give you several sites.  Choose one of them,  on your choice.  They all are free of charge.

Take,  for example,  this one
https://www.statskingdom.com/linear-regression-calculator.html

Input your data and press the button  " Calculate ".

You will get the answer in the next second,
with all needed explanations,  formulas,  theory etc.


It is like free of charge hospital,  where you will get
the best possible treatment,  and will go out completely healthy and with enlightened brain.


Moreover,  next time you will know  " WHAT  TO  DO " and will be able
to solve similar problems on your own,  which is your lovely dream  (as I  firmly believe).
