Answer 2

It's new method to me?????

Answer 3

@phi is it ok, phi?

Answer 4

@mirandajohanson I put your data into excel and get best fit at y = 3.3045x
I don't know what you are calculating on those data but the way you get the equation is totally weird to me.

Answer 5

let's wait for phi or someone else correct it.
