PSLE The graph shows the height of a plant from April to August.
- What was the height of the plant in August?
- During which period did the plant have no change in height? 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) = 29 cm
Height of the plant in July (7) = 37 cm
Height of the plant in August (8) =
42 cm Height of the plant in August (7) = 42 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) = 29 - 29 =
0 cm Increase in height from June (6) to July (7) = 37 - 29 = 8 cm
Increase in height from July (7) to August (8) = 42 - 37 = 5 cm
Period which the plant grew the least = May (5) to June (6)
Answer(s): (a) 42 cm; (b) 5 to 6
