Let's solve the problem step by step using the data provided in the worksheet.
---
Given Data:
| Week | Height (cm) |
|------|-------------|
| 1 | 2 |
| 2 | 5 |
| 3 | 8 |
| 4 | 11 |
| 5 | 14 |
We are to:
1. Draw a line graph using this data.
2. Answer five questions based on the data and graph.

Step 1: Drawing the Line Graph
To draw the line graph:
- On the
x-axis, label weeks: Week 1 to Week 5.
- On the
y-axis, label height in centimeters from 0 to 16 cm.
- Plot each point:
- (Week 1, 2 cm)
- (Week 2, 5 cm)
- (Week 3, 8 cm)
- (Week 4, 11 cm)
- (Week 5, 14 cm)
- Connect the points with straight lines.
The plant grows steadily over time, so the line will be increasing at a constant rate.

Now, answer the questions:

####
1. How tall was the plant in week 2?
From the table:
Answer: 5 cm
---
####
2. How much had the plant grown from week 1 to week 2?
- Week 1: 2 cm
- Week 2: 5 cm
- Growth = 5 – 2 =
3 cm
Answer: 3 cm
---
####
3. How much had the plant grown from week 2 to week 4?
- Week 2: 5 cm
- Week 4: 11 cm
- Growth = 11 – 5 =
6 cm
Answer: 6 cm
---
####
4. How much had the plant grown from week 1 to week 5?
- Week 1: 2 cm
- Week 5: 14 cm
- Growth = 14 – 2 =
12 cm
Answer: 12 cm
---
####
5. On week 6, do you think the plant would be around 21 cm or 17 cm?
Let’s look at the pattern of growth:
- Week 1 → 2
- Week 2 → 5 → +3 cm
- Week 3 → 8 → +3 cm
- Week 4 → 11 → +3 cm
- Week 5 → 14 → +3 cm
So, the plant grows
3 cm per week.
Therefore, in
Week 6, it should grow another 3 cm:
- 14 cm (Week 5) + 3 cm =
17 cm
Answer: 17 cm

✔ Final Answers:
1.
5 cm
2.
3 cm
3.
6 cm
4.
12 cm
5.
17 cm

📈 Summary:
The plant grows
3 cm per week consistently. This is a linear pattern, so we can predict future heights by adding 3 cm each week.
This is a great example of how graphs and patterns help us understand real-world data like plant growth!
