Question

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

Explanation:

Step1: Recall line - of - best - fit concept

The 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 each graph

• In the first graph, the horizontal line does not capture the upward or downward trend of the data well.
• In the second graph, the line has a very steep slope and does not seem to be centered among the data points.
• In the third graph, the line passes through the middle of the data points and follows the general upward trend of the data.
• In the fourth graph, the negative - sloped line does not match the overall upward trend of the data.

Answer:

The third graph shows the line of best fit for the data.
