Question

Practice using tables and graphs of linear functions to find unknown information.
Taleen has 8 stamps in her collection, and she decides that each month she will add 3 stamps to her collection.

What does the rate of change represent?

What is the rate of change?

What does the initial value represent?

What is the initial value?

Answer 1

Let m = months since she started. The number of stamps S(m) is a linear function S(m) = 8 + 3m.

- What does the rate of change represent?
- It represents how many stamps the collection increases by each month.

- What is the rate of change?
- 3 stamps per month.

- What does the initial value represent?
- It represents the number of stamps at month 0 (the starting amount).

- What is the initial value?
- 8 stamps.
