Part B Natalie also made a catapult, but she used stronger elastic bands than Aiden did. As a result, she was able to send her ball farther with a shorter arm length. She also varied the length of her catapult arm while measuring the horizontal distance between where the tennis ball was launched and where it landed. The table presents the data she recorded while using her catapult.

Length of Catapult Arm (cm) Horizontal Distance (cm)
25 290.8
35 325.4
30 315.2
60 420
65 435.8
50 385.1
45 355
40 362
50 378.3
40 333.9

Use the graphing tool to determine the line of best fit for Natalie’s data.
