Which of the following best approximates the line of best fit?
sorry that it's hard to see

Answer:
A
Step-by-step explanation:
Remark
The line that has the best fit is one who distance above the line is the same as the distance below the line.
That statement means that if you take each point above the line and measure its (perpendicular) distance to the line and add all the distances of those points above the line together, you should get the same distance for the points below the line.
So why is A the best answer?
It's because the distance of the three points above the line should come close to the distance the 3 points are below the line.
