Answer:
The correct option is 1.
Step-by-step explanation:
The given table is
Quantity(x) Â Â Price(y)
  1          2.00
  2         3.50
  3         5.00
  4         6.50
  5         8.00
  6         9.00
It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).
The graph 1 represents all the above mentioned point, therefore option 1 is correct.
According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.
The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.
Therefore the option 3 and 4 are incorrect.
