In an experiment involving two variables, time (t), hours and height, (h) ; the following results were obtained.
Time )t) hours | 0 | 0.7 | 1.5 | 2.1 | 2.8 | 3.2 | 3.6 |
Height (h) cm | 100 | 82 | 64 | 46 | 32 | 18 | 10 |
- On the grid provided, plot (1, h) where t is time and h is the height.
- Use the plotted points to draw the line of best fit for the data and hence determine the rate of change of height with time.
