A scientist collects data on the growth of a certain plant species, measuring its height in centimeters () at different ages in weeks (). The line of best fit for this data is modeled by the equation .
Based on this equation, what does the value represent in the context of the plant's growth?
The initial height of the plant when it was 0 weeks old.
The predicted height of the plant after 0.8 weeks.
The average increase in plant height, in centimeters, for each additional week of age.
The maximum height the plant is expected to reach.
