This is true, because the LSRL does get its line when minimizing the sum of the squares difference between the observed (x value) and predicted (y-at)
use the pythagorean theorem: a^2 + b^2 = c^2
6^2 = 36
4^2 = 16
36-16 = 20.
the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
