A student investigates the extension of a steel spring when different weights are suspended from it. The experimental setup is illustrated in the diagram below:
The results of the investigation are shown in the table:
| Weight (N) | Extension (cm) |
|---|---|
| 1.0 | 1.5 |
| 2.0 | 3.0 |
| 3.0 | 4.5 |
| 4.0 | 6.0 |
| 5.0 | 7.5 |
| 6.0 | 9.0 |
Draw a line graph of these results on the grid below.
