(pic)

Which statement is most likely correct about the line?


A) It can be a line of best fit because it is closest to most data points.

B) It can be a line of best fit because it passes through all the data points.

C) It cannot be a line of best fit because it does not pass through all the points.

D) It cannot be a line of best fit because it does not pass through the first and last points.

Answer 1

A) It can be a line of best fit because it is closest to most data points.

Explanation:

Recall that the line of "best fit" is the line that minimizes the distance to all plotted points. It doesn't have to go through all of the date points since they may not be perfectly aligned. It also doesn't have to go through the first and last points either.
