Would be interesting to see a visualization of "how close" your estimated line is to the actual line (or numerically how similar their slopes are).
It does look close to my eyes though, and I'm sure I could plug it into a calculator (or paintstakingly work the formulas out by hand).

That's tha part that I like so much,linear regression but with linear algebra is powerfull!
Great stuff❤
