2003



2004



2005



2006



Number of patients:



150



170



195



225



230



Represent this information by a graph.

Here, we take years on the x-axis and the number of patients on the y-axis.


Let us choose the following scale:
On x-axis: 1 cm = 1 year
On y-axis: 1 cm = 10 patients


Now, let us plot (2002, 150), (2003, 170), (2004, 195), (2005, 225), (2006, 230). These points are joined to get the graph representing the given information as shown in the figure below.


Scale:


On x axis: 1cm = 1year


On y-axis: 1 cm = 10 patients
