PSLE The graph shows the height of a plant from May to September.
- What was the height of the plant in June?
- During which period did the plant grow the least? Give your answer in numbers. (Eg Jan to Feb = 1 to 2)
(a)
Height of the plant in May (5) = 39 cm
Height of the plant in June (6) =
48 cm Height of the plant in July (7) = 60 cm
Height of the plant in August (8) = 71 cm
Height of the plant in September (9) = 72 cm
Height of the plant in June (6) = 48 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from May (5) to June (6) = 48 - 39 = 9 cm
Increase in height from June (6) to July (7) = 60 - 48 = 12 cm
Increase in height from July (7) to August (8) = 71 - 60 = 11 cm
Increase in height from August (8) to September (9) = 72 - 71 =
1 cm Period which the plant grew the least = August (8) to September (9)
Answer(s): (a) 48 cm; (b) 8 to 9
