Let’s solve each problem step by step.

Problem 1: Plant Height at Week 1, 2, and 3
We are given a line graph showing the height of a plant (in cm) over weeks.
- The x-axis shows “weeks” from 0 to 4.
- The y-axis shows “height (cm)” from 0 to 5.
- We need to find the height at
Week 1,
Week 2, and
Week 3.
Look at the points on the graph:
- At
Week 1: Go up from “1” on the x-axis until you hit the red dot. Then look left to the y-axis — it lines up with
2 cm.
- At
Week 2: Go up from “2” on the x-axis → red dot is at
3 cm.
- At
Week 3: Go up from “3” on the x-axis → red dot is at
5 cm.
✔ So:
- Week 1 = 2 cm
- Week 2 = 3 cm
- Week 3 = 5 cm

Problem 2: Total Goals Barbra Scored in 13 Practice Sessions
We are given a line graph titled “How many goals did Barbra score during all her 13 practice sessions?”
- X-axis: “practice session” from 1 to 15 (but we only care about sessions 1 to 13).
- Y-axis: “Goals scored” from 0 to 6.
- We must add up the number of goals for each session from 1 to 13.
Let’s read the value for each session:
Session 1 → 2
Session 2 → 1
Session 3 → 0
Session 4 → 2
Session 5 → 5
Session 6 → 3
Session 7 → 5
Session 8 → 4
Session 9 → 0
Session 10 → 0
Session 11 → 6
Session 12 → 0
Session 13 → 0
Now let’s add them step by step:
Start adding:
2 + 1 = 3
3 + 0 = 3
3 + 2 = 5
5 + 5 = 10
10 + 3 = 13
13 + 5 = 18
18 + 4 = 22
22 + 0 = 22
22 + 0 = 22
22 + 6 = 28
28 + 0 = 28
28 + 0 = 28
✔ Total goals =
28

Final Answer:
Week 1: 2 cm, Week 2: 3 cm, Week 3: 5 cm; Total goals: 28
