An illustration shows a scatterplot titled Number of Laps the Swim Team Completes Per Week. The x-axis shows weeks ranging from 1 through 10 in increments of one. The y-axis shows number of laps and ranges from 100 to 1,000 in 100 unit increments.
Eight points are plotted on the graph. A kink is shown on both the x- and y-axes close to the origin to indicate a break in the data. The points are plotted at approximate coordinates left parenthesis 1 comma 50 right parenthesis, left parenthesis 2 comma 150 right parenthesis, left parenthesis 3 comma 200 right parenthesis, left parenthesis 4 comma 300 right parenthesis, left parenthesis 5 comma 500 right parenthesis, left parenthesis 6 comma 600 right parenthesis, left parenthesis 7 comma 700 right parenthesis, and left parenthesis 8 comma 800 right parenthesis.

The scatterplot depicts a pattern where the number of laps completed by the swim team increases as the weeks progress. The plotted points show a rising trend, indicating that as the weeks increase, the number of laps also increases. This suggests a positive association between the number of weeks and the number of laps completed.
Given that the data points appear to follow a roughly linear pattern, the most appropriate interpretation is:
The graph shows a positive linear association.
