LINE GRAPH

Line graph is a type of graph that shows the relationship between two quantities by
connecting them with a straight line. The most common use for line graphs is to show the

change in one quantity over time.
Example: The table below shows the data on how much sleeping time of Rama in each
night for a week.

Days Mon Tue Wed Thu Fri Sat Sun
No. of Hours 6.5 7 7.5 6 6.5 8.5 8

Draw a line graph for the information provided.

Solution: To draw the line graph for the information provided, we follow these steps:
Step 1: Label the number of hours on the y-axis and the days on the x-axis.

Step 2: Next, we mark points for the given data:
Mon = 6.5 Tue = 7 Wed = 7.5 Thu = 6 Fri = 6.5 Sat = 8.5 Sun = 8

Step 3: Now join the points successively. Rama's Sleeping Hours for a Week
Thus, the line graph for the given 10
8
information is obtained as shown 6
below. 4

We can also interpret the line graph drawn here for No. of Hours 2
various questions. 0 Mon Tue Wed Thu Fri Sat Sun

For example, Days
1. In which day did Rama sleep maximum hours? Saturday

2. In which day did Rama sleep minimum hours? Thursday
3. How many hours did sleep on Wednesday? 7.5 hours
