Drawing a line graph (broken line graph) worksheet: Answers and working

1. 9 squares
The side starts at 0, 50 a square. How many lots of 50 are there in 450?
450 ÷ 50 = 9.
2. 9 squares
The side starts at 0, 5 a square. How many lots of 5 are there in 45?
45 ÷ 5 = 9.
3. 7 squares
Work out 69 ÷ 10. The biggest number must fit on, so what if it isn't whole?
69 ÷ 10 isn't whole, so round up: 7 squares fit it.
4. 12 squares
Work out 231 ÷ 20. The biggest number must fit on, so what if it isn't whole?
231 ÷ 20 isn't whole, so round up: 12 squares fit it.

5. B
Read off each graph's points in order, Monday to Thursday: 34, 18, 22, 18.
Read each point back: 34, 18, 22, 18 — the order and the values must both match.
6. B
Read off each graph's points in order, Monday to Thursday: 22, 24, 18, 28.
Read each point back: 22, 24, 18, 28 — the order and the values must both match.
7. B
Read off each graph's points in order, Monday to Thursday: 30, 18, 34, 18.
Read each point back: 30, 18, 34, 18 — the order and the values must both match.
8. D
Read off each graph's points in month order and check them against 25, 50, 35, 45, 5.
Read each point back in month order: 25, 50, 35, 45, 5.
9. D
Read off each graph's points in month order and check them against 35, 40, 20, 50, 20.
Read each point back in month order: 35, 40, 20, 50, 20.
10. True
First see where the side starts and what a square stands for, then read each point and compare with the list.
Read each point back: the side starts at 16, 2°C a square; every point must match the table.
11. False
First see where the side starts and what a square stands for, then read each point and compare with the list.
Read each point back: the side starts at 16, 2°C a square; every point must match the table.
12. True
First see where the side starts and what a square stands for, then read each point and compare with the list.
Read each point back: the side starts at 16, 2°C a square; every point must match the table.

Marking: 2 for the working, 1 for the answer, 1 for the sentence.

13. A
Read off each graph's points in week order and check them against 4, 6, 12, 18.
Read each point back in week order: 4, 6, 12, 18.
14. 3 squares
First find the rise, 90 − 60, then how many lots of 10 that is.
It rises 90 − 60; at 10 a square, that is 3 squares.
15. 16 squares
Work out 15,200 ÷ 1000. The biggest day must fit on, so what if it isn't whole?
15,200 ÷ 1000 isn't whole, so round up: 16 squares.
16. A
Read off each graph's points in week order and check them against 2, 6, 10, 16.
Read each point back in week order: 2, 6, 10, 16.
17. 1 square
First find the rise, 30 − 25, then how many lots of 5 that is.
It rises 30 − 25; at 5 a square, that is 1 squares.
18. 10 squares
Work out 9,400 ÷ 1000. The biggest day must fit on, so what if it isn't whole?
9,400 ÷ 1000 isn't whole, so round up: 10 squares.
