The following table shows the number of patients discharged from a hospital with HIV diagnosis in different years:

Years: | 2002 | 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
