A coordinate plane is titled: Number of Laps Swam. It shows day on the x-axis from 0 to 7 in increments of 1. It shows number of laps on the y-axis from 0 to 20 in increments of 1.
The approximate data points are as follows: left parenthesis 1 comma 18 right parenthesis, left parenthesis 2 comma 21 right parenthesis, left parenthesis 3 comma 14 right parenthesis, left parenthesis 4 comma 15 right parenthesis, left parenthesis 5 comma 11 right parenthesis, left parenthesis 6 comma 15 right parenthesis, and left parenthesis 7 comma 9 right parenthesis.

To find the correct scatterplot, we will first summarize the data from the table:
Day 1: 18 laps
Day 2: 12 laps
Day 3: 10 laps
Day 4: 15 laps
Day 5: 13 laps
Day 6: 20 laps
Day 7: 9 laps
Now we will compare this data against the approximate data points provided in each option:
First Option:
(2, 21) → Incorrect (should be 12)
(3, 14) → Incorrect (should be 10)
(5, 11) → Incorrect (should be 13)
(6, 15) → Incorrect (should be 20)
This option has multiple inaccuracies.
Second Option:
(1, 18) → Correct
(2, 12) → Correct
(3, 10) → Correct
(4, 15) → Correct
(5, 13) → Correct
(6, 20) → Correct
(7, 9) → Correct
This option accurately represents the data from the table.
Third Option:
(3, 8) → Incorrect (should be 10)
This option has one error initially.
Fourth Option:
(6, 14) → Incorrect (should be 20)
This option has one error initially.
After going through the options, the second option is the only one that correctly represents the number of laps swam by the student each day.
So, the correct answer is the second scatterplot option.
