Question

which graph shows a line of best fit for the data?

Explanation:

Step1: Recall line - of - best - fit concept

A line of best fit should be drawn in such a way that the points are evenly distributed around the line. It represents the general trend of the data points.

Step2: Analyze Option A

The line in Option A does not follow the general trend of the data points. The data points seem to be decreasing overall, while the line in Option A is increasing.

Step3: Analyze Option B

The line in Option B seems to follow the general decreasing trend of the data points. The points are relatively evenly distributed around this line.

Step4: Analyze Option C

The line in Option C does not fit the data well as the data points are not evenly distributed around it. There is a large gap between the line and some of the data points on the right - hand side.

Step5: Analyze Option D

The horizontal line in Option D does not capture the decreasing trend of the data points.

Answer:

B.
