Answer:
Explanation:
This situation can be modeled by a linear equation since it has a constant rate of change. Linear functions are represented in the slope-point form by:
The slope can be calculated as:
Given the information on the table, we can use the points (3, 15) and (5,25):
A. Then, by the slope-point form we can model the situation:
B. Now, to predict the height of the plant after 12 months, substitute x=12 into the equation:
