A line graph shows the growth of a plant over five weeks: Week 1: 5cm, Week 2: 10cm, Week 3: 15cm, Week 4: 20cm, Week 5: 25cm. What is the growth rate per week?

Step 1: Identify the height of the plant at the beginning (Week 1) and the end (Week 5).
Step 2: The height at Week 1 is 5cm and at Week 5 is 25cm.
Step 3: Calculate the total growth by subtracting the height at Week 1 from the height at Week 5: 25cm - 5cm.
Step 4: This gives us a total growth of 20cm.
Step 5: Count the number of weeks between Week 1 and Week 5. There are 4 weeks (Week 2, Week 3, Week 4, Week 5).
Step 6: To find the growth rate per week, divide the total growth (20cm) by the number of weeks (4): 20cm / 4 weeks.
Step 7: This gives us a growth rate of 5cm per week.
