PSLE The graph shows the height of a plant from February to June.
- What was the height of the plant in March?
- 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 February (2) = 33 cm
Height of the plant in March (3) =
42 cm Height of the plant in April (4) = 49 cm
Height of the plant in May (5) = 59 cm
Height of the plant in June (6) = 61 cm
Height of the plant in March (3) = 42 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) = 42 - 33 = 9 cm
Increase in height from March (3) to April (4) = 49 - 42 = 7 cm
Increase in height from April (4) to May (5) = 59 - 49 = 10 cm
Increase in height from May (5) to June (6) = 61 - 59 =
2 cm Period which the plant grew the least = May (5) to June (6)
Answer(s): (a) 42 cm; (b) 5 to 6
