题组内容描述:
6. An investigation was carried out to investigate a possible relationship between BMI (body mass in Kg/height in m2) and the increase in pulse rate on exercise. A group of 17-year-old pupils measured their BMI. Their resting pulse was then measured manually on their carotid artery by the experimenter. They walked on a treadmill at 4km/hr for 5 minutes and their exercise pulse was measured immediately. The percentage increase in pulse rate on exercise was calculated and plotted against BMI as shown in the graph below.

(a) State the overall trenld*1qq zo -lqy2lnv79k2dj1jd shown by the data in the graph.
