Four scatter plots are shown. Each plot has a set of data points represented by small, dark dots.
* **A.** The data points are clustered roughly along a horizontal line.
* **B.** The data points roughly follow a diagonal line from the bottom left to the upper right.
* **C.** Similar to plot A, the data points are clustered roughly along a horizontal line.
* **D.** The data points show a vertical relationship, clustered roughly along several vertical lines.
Which of the graphs is the best example of a line of best fit?

A AA
B BB

The best example of a line of best fit would be **B**. In plot B, the data points roughly follow a diagonal line from the bottom left to the upper right, indicating a positive correlation between the two variables. A line of best fit is typically used to represent the relationship in such cases, where there is a clear trend or pattern in the data. Plots A and C suggest little to no correlation, while plot D suggests a vertical relationship that does not lend itself to fitting a line effectively.
