Louis tracks changes in his running time, in minutes, over a number of weeks. He records how long it takes him to run 5 kilometers once a week for 8 weeks. The table shows his data: Week | Time (minutes) 1 | 52 2 | 53 3 | 49 4 | 50 5 | 50 6 | 47 7 | 48 8 | 47 Use the Connect Line tool to create a line graph of Louis's data.

• The correct line graph should have points at (1,52), (2,53), (3,49), (4,50), (5,50), (6,47), (7,48), (8,47) and connect them in order.

• The correct line graph should have points at (1,47), (2,48), (3,50), (4,49), (5,53), (6,52), (7,50), (8,47) and connect them in order.
