Question

each point on the scatter plot represents the cost of a first - class postage stamp in the united states at the end of each year. which line is the line of best fit?
options: line b, line c, line a, line d

Explanation:

Step1: Recall Line of Best Fit

The line of best fit should pass through the middle of the scatter points, balancing the number of points above and below it.

Step2: Analyze the Graphs

Looking at the scatter plot (even with partial view), the line that best represents the trend (minimizing distance to most points) is Line B (assuming from typical line - of - best - fit logic for such postage - cost - over - time data, where the line should follow the general upward trend of the points closely).

Answer:

Line B
