When you receive Plant A, it is 4 cm tall, and it grows at a constant rate of 2 cm per month.

Question

Write an equation that can be used to find the height of Plant A after any number of months. Use t to represent the time in months, and let h represent the height of the plant in cm.

Answer 1

To find the height of Plant A after any number of months, you can use a linear equation. Given that the initial height of the plant is 4 cm and it grows at a constant rate of 2 cm per month, the equation can be formulated as follows:

\[ h = 4 + 2t \]

In this equation:

• \( h \) represents the height of the plant in centimeters.
• \( t \) represents the time in months.
• The term \( 4 \) is the initial height of the plant.
• The term \( 2t \) represents the growth of the plant over \( t \) months, with 2 cm of growth per month.
