Question

select the correct answer.
maggie drew lines of best fit for two scatter plots, as shown.
which statement best describes the placement of the lines maggie 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: Analyze Line A

A line of best fit should approximate the trend of the data points. For Line A, observe the scatter plot: the line seems to follow the general upward trend of the points, with points relatively evenly distributed around it.

Step2: Analyze Line B

For Line B, the line follows the general downward trend of its scatter plot's points, with points reasonably distributed around it.

Step3: Evaluate Options

• Option A: Incorrect, as Line B also fits.
• Option B: Incorrect, as Line A also fits.
• Option C: Correct, since both lines follow their respective data trends.
• Option D: Incorrect, as both lines are well - placed.

Answer:

C. Both line A and line B are well - placed lines of best fit.
