Question

naomi drew lines of best fit for two scatter plots, as shown. which statement describes the placement of the lines naomi drew? a. only line a is a well - placed line of best fit. b. only line b is a well - placed line of best fit. c. both line a and line b are well - placed lines of best fit. d. neither line a nor line b is a well - placed line of best fit.

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 vertical distances from the points to the line.

Step2: Analyze Line A

In the scatter - plot with Line A, the line does not seem to be close to most of the data points. There are many points that are far away from the line, and the line does not represent the overall trend of the data well.

Step3: Analyze Line B

In the scatter - plot with Line B, the line also does not seem to be close to most of the data points. There are several points that deviate significantly from the line, and it does not accurately capture the trend of the data.

Answer:

D. Neither line A nor line B is a well - placed line of best fit
