Question

The table represents the cost of flowers at the Tigerlily Flower Shop.

Quantity Price
1 2.00
2 3.50
3 5.00
4 6.50
5 8.00
6 9.00
Which graph is the best interpretation of this table?
(The Table is messed up a bit but the decimal numbers are the price and the 1,2,3,4,5, and 6 are quantity.)

Answer 1

The first graph would be correct. 

Answer 2

The correct option is 1.

Explanation:

The given table is

Quantity(x) 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.
