how do we find the best statement that describes the placements that the person drew?
Maggie drew lines of best fit for two scatter plots, as shown.
Two scatterplots are given. The first scatterplot has a decreasing line passing through the plotted points and is labeled, line A. The second scatterplot has an increasing line passing through the plotted points and is labeled, line B.
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.
To determine the best statement that describes the placements that the person drew, we need to analyze the scatterplots and the lines of best fit.
From the description, line A is a decreasing line passing through the plotted points in the first scatterplot, while line B is an increasing line passing through the plotted points in the second scatterplot.
To determine if the lines of best fit are well-placed, we need to consider if they accurately represent the general trend or relationship between the variables being plotted. The goal of a line of best fit is to approximate the overall pattern of the data points.
Looking at the first scatterplot, if the points generally follow a decreasing trend, then line A can be considered as a well-placed line of best fit.
Looking at the second scatterplot, if the points generally follow an increasing trend, then line B can be considered as a well-placed line of best fit.
Therefore, the best statement that describes the placements that the person drew is:
C. Both line A and line B are well-placed lines of best fit.
