The document discusses key features of line graphs, including having a title, labeled axes with regular intervals, and data points plotted on the axes rather than between them. It provides an example line graph showing monthly temperature data for Lake Tekapo. Learners are instructed to create their own line graph using sample Maori population data from New Zealand from 1901 to 1981, with guidance on properly plotting the data and axes.

The Line Graph

2. Key Features of a Line Graph
A Line Graph should have the same key
points to it as a Bar Graph:
• A Title
• Both axis ruled
• Clearly labelled unit of measurement on
both axis
• Equal spacing on both axis
• Numbers increasing at regular intervals

3. Key Features of a Line Graph
A Line Graph should have the same key
points to it as a Bar Graph:
• The only main difference is that the
horizontal labels should be on the point
instead of in between the points

6. Create your own Line Graph
• Use these figures to create your
own line graph.
• Remember the Key Features of a
Line Graph.
• Hint: Decide on vertical axis
spacing now.
• Be careful when plotting the
years as not all the figures are in
10 year intervals.
• Complete graph and then put
your hand up so I can check your
graph.

8. Maori Population in New Zealand
• Now you have completed your graph I
want you to write 2-3 sentences describing
what your graph is showing.
• e.g. The above line graph is showing . . .

9. Maori Population in New Zealand
• Now answer these questions about your
completed graph.
• Between which 10 year period was the
biggest increase in population?
• Between which 10 year period was the
lowest increase in population? 1911-1921
1971-1981
