Each day, Talisa exercises by first stretching and then swimming some laps, as shown in the table. Use the table of her exercise data to choose the scatter plot with the best trend line.
Laps 5 6 7 8 9
Time (min) 25 28 29 30 32
A. A graph showing data on Number of Laps from 0 to 12 at an interval of 2 on x-axis and Total Time (mins) from 0 to 60 at an interval of 10 on y-axis is given. 5 dots are plotted on the graph on co-ordinates (4,26), (6,31), (8,39), (10,45) and (12,50). A straight line is drawn passing through all the dots.
B. A graph showing data on Number of Laps from 0 to 12 at an interval of 2 on x-axis and Total Time (mins) from 0 to 60 at an interval of 10 on y-axis is given. 5 dots are plotted on the graph on co-ordinates (4.5,26), (6.2,31), (8,39), (10,45) and (12,50). A straight line is drawn passing through all the dots.
C. A graph showing data on Number of Laps from 0 to 12 at an interval of 2 on x-axis and Total Time (mins) from 0 to 60 at an interval of 10 on y-axis is given. 5 dots are plotted on the graph on co-ordinates (5,25), (6,28), (7,29), (8,30) and (9,32). A straight line is drawn passing through all the dots.
D. A graph showing data on Number of Laps from 0 to 12 at an interval of 2 on x-axis and Total Time (mins) from 0 to 60 at an interval of 10 on y-axis is given. 5 dots are plotted on the graph on co-ordinates (4.5,25), (6.2,32), (8.1,40), (10,45) and (12,54). A straight line is drawn passing through all the dots.
