medium · Enhanced ACT science
An environmental scientist measures the light intensity at different depths in a lake.
| Depth (m) | Intensity (lux) |
|:---|:---|
| 0 | 1,200 |
| 5 | 950 |
| 10 | 700 |
| 15 | 450 |
If the trend continues linearly between the measurements, what is the light intensity at a depth of 4 meters?
- 950 lux
- 1,150 lux
- 1,000 lux
- 1,075 lux
