Here, we take the number of persons on the x-axis and time taken on the y-axis.
Let us choose the following scale:
On x-axis: 1 cm = 1 person
On y-axis: 1 cm = 1 day Now, let us plot (2, 12), (4, 6), (6, 4), (8, 3).
These points are joined to get the graph representing the given information as shown in the figure below.
Scale:
On x axis: 1 cm = 1 person
On y-axis: 1 cm = 1 day
