Question
Use the image to answer the question.
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.
Interpret the scatterplot to determine what type of association the scatterplot shows.(1 point)
Responses

The graph shows no association.
The graph shows a negative linear association.
The graph shows a negative linear association.
The graph shows a positive linear association.
The graph shows a positive linear association.
The graph is non–linear.
1 answer
The scatterplot exhibits a positive linear association. As the number of weeks (x-axis) increases, the number of laps completed per week (y-axis) also increases. The points appear to be moving upward from left to right, indicating that there is a direct relationship between the two variables. Therefore, the correct response is:
The graph shows a positive linear association.
