Question

The population of rabbits over a duration in a zoo is tabulated as follows:
Year Population of Rabbit
(in thousand)

2015	4
2016	5
2017	6
2018	7
2019	8
2020	9

Choose the line graph that correctly depicts the data set.

• A.
• B.

Answer 1

The correct option is A

Year Population of Rabbit
(in thousand)

2015	4
2016	5
2017	6
2018	7
2019	8
2020	9

Let's represent the horizontal axis in a year and the vertical axis as a population of rabbits (in thousands).

To choose the scale of the vertical axis, we observe the minimum and maximum values of the population.

The minimum and maximum values of the population of rabbits (in thousands) are 4 and 9 respectively.

$\therefore$ The vertical axis can start from 0 to 10 units with an interval of 2 units, such that the whole area of the graph can be utilized.

Plotting the population year by year, we obtain the following graph:
