which of the graphs is the best example of a line of best fit? a a b b c c d d

Brief Explanations:

A line of best - fit is a straight line that best represents the data on a scatter - plot. It should be positioned so that the points are evenly distributed around it. In option C, the line is placed in such a way that the points are symmetrically scattered around it, which is characteristic of a good line of best - fit. In option A, the line does not seem to account for the overall trend of the points. In option B, the line is not centered among the points. In option D, the line does not represent the general pattern of the points well.

Answer:

C.
