I wonder what is your best fit criterion.

Your line does not look like a best fit to your four points

My estimate for your points joins (2.5,7.5) and (5.5,0.5)

My four are (2,8) (0,6) (5,1) (7,3)

When creating this problem, I was initially thinking it as 8th grade, where they informally justify a line of best fit. Thank you for your points!
