LINE GRAPH

Line graphs are used to show trends over a period of time and have the advantage that they can be extended. To draw a line graph, plot the given data as a series of points and then join the points together by straight lines. The lines can be drawn vertically or horizontally and have no thickness.

Example 1

A comparison of traffic densities in a number of countries produced the following results.

Present the data in a line graph

Solution:

Example 2:

The table below shows the number of eggs laid in one month by 5 hens. Draw a horizontal line graph for the data.

Class Activity:

1. The student population of the Federal Government college Kano was recorded as follows.
