PSLE The graph shows the height of a plant from June to October.
- What was the height of the plant in August?
- During which period did the plant grow the most? Give your answer in numbers. (Eg Jan to Feb = 1 to 2)
(a)
Height of the plant in June (6) = 15 cm
Height of the plant in July (7) = 22 cm
Height of the plant in August (8) =
32 cm Height of the plant in September (9) = 47 cm
Height of the plant in October (10) = 57 cm
Height of the plant in August (8) = 32 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from June (6) to July (7) = 22 - 15 = 7 cm
Increase in height from July (7) to August (8) = 32 - 22 = 10 cm
Increase in height from August (8) to September (9) = 47 - 32 =
15 cm Increase in height from September (9) to October (10) = 57 - 47 = 10 cm
Period which the plant grew the most = August (8) to September (9)
Answer(s): (a) 32 cm; (b) 8 to 9
