An agricultural scientist is researching the relationship between the soil nitrogen content, NNN (measured in grams per square meter, g/m2\text{g/m}^2g/m2), and the dry biomass yield of a wheat cultivar, YYY (measured in tonnes per hectare, t/ha\text{t/ha}t/ha).
The results for 9 experimental plots are shown in the table below:
Table 1: Soil nitrogen content and dry biomass yield for 9 experimental plots
| Plot | A | B | C | D | E | F | G | H | I |
|---|---|---|---|---|---|---|---|---|---|
| Soil Nitrogen Content, NNN (g/m2\text{g/m}^2g/m2) | 1.5 | 2.8 | 3.5 | 4.2 | 5.0 | 6.4 | 7.2 | 8.0 | 9.5 |
| Dry Biomass Yield, YYY (t/ha\text{t/ha}t/ha) | 3.2 | 4.5 | 4.1 | 5.8 | 6.2 | 7.0 | 6.8 | 8.1 | 8.5 |
Draw a suitable graphical display to represent the data in Table 1. Label your graph appropriately.
