Answer

Explanation:

Step1: Recall line - of - best - fit concept

A line of best fit should be as close as possible to all the data points in a scatter - plot, minimizing the sum of the squared vertical distances from the points to the line.

Step2: Analyze Line A

Line A appears to be close to most of the data points in its scatter - plot, representing the general trend of the data well.

Step3: Analyze Line B

Line B does not seem to represent the general trend of the data points in its scatter - plot well. There are several points that are far from the line and the line does not capture the overall pattern of the data.

Answer:

A. Only line A is a well - placed line of best fit.
