Question

A plant is already 9 centimeters tall, and it will grow one centimeter every month.

Let be the plant's height (in centimeters) after months.


Write an equation relating to . Then graph your equation using the axes below.

Answer 1

p + (m × 1) = t

If a plant is already ___cm tall and it will grow one cm every month, an equation to find out how much the plant grew in __ months is this:

(Let t = total number of centimeters, m = number of months, and p = the length of the plant already.)

• p + (m × 1) = t

Therefore, the equation you can use is p + (m × 1) = t.
