PSLE The graph shows the height of a plant from February to June.
- What was the height of the plant in April?
- 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 February (2) = 22 cm
Height of the plant in March (3) = 31 cm
Height of the plant in April (4) =
37 cm Height of the plant in May (5) = 49 cm
Height of the plant in June (6) = 55 cm
Height of the plant in April (4) = 37 cm
(b)
To find the greatest increase, look for the steepest increase in the line graph.
To prove:
Increase in height from February (2) to March (3) = 31 - 22 = 9 cm
Increase in height from March (3) to April (4) = 37 - 31 = 6 cm
Increase in height from April (4) to May (5) = 49 - 37 =
12 cm Increase in height from May (5) to June (6) = 55 - 49 = 6 cm
Period which the plant grew the most = April (4) to May (5)
Answer(s): (a) 37 cm; (b) 4 to 5
