Question

select the correct answer.
trevor drew lines of best fit for two scatter plots, as shown.
which statement describes the placement of the lines trevor 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 the concept of line of best fit

A line of best fit should pass through the middle of the data points in a scatter - plot, with approximately equal number of points on either side of the line.

Step2: Analyze Line A

For Line A, the points are somewhat evenly distributed around the line. There are points above and below the line in a relatively balanced way.

Step3: Analyze Line B

For Line B, the points are not evenly distributed around the line. Most of the points are either above or below the line in an unbalanced manner.

Answer:

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