PSLE The graph shows the height of a plant from April to August.
- What was the height of the plant in July?
- 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 April (4) = 23 cm
Height of the plant in May (5) = 29 cm
Height of the plant in June (6) = 33 cm
Height of the plant in July (7) =
45 cm Height of the plant in August (8) = 55 cm
Height of the plant in July (7) = 45 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from April (4) to May (5) = 29 - 23 = 6 cm
Increase in height from May (5) to June (6) = 33 - 29 =
4 cm Increase in height from June (6) to July (7) = 45 - 33 = 12 cm
Increase in height from July (7) to August (8) = 55 - 45 = 10 cm
Period which the plant grew the least = May (5) to June (6)
Answer(s): (a) 45 cm; (b) 5 to 6
