Question

select the correct answer. nancy drew lines of best - fit for two scatter plots, as shown. which statement describes the placement of the lines nancy 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 is a straight line that best represents the data on a scatter - plot. It should be as close as possible to most of the data points.

Step2: Analyze Line A

Line A does not seem to pass through the "center" of the cluster of points. There are many points that are far from the line, so it is not a well - placed line of best fit.

Step3: Analyze Line B

Line B also does not seem to be optimally placed. There are several points that are quite far from the line, and it does not seem to capture the overall trend of the data well.

Answer:

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