This video explains all the important features of a line graph.
A dachshund puppy is weighed every two weeks.
Construct a line graph of the information given in the table.
How much weight had the puppy gained from week 2 to week 4?
In which weeks did the puppy's weight not change?
Line graphs use connected points plotted in a number plane to show data.
This video shows us how to create a line graph and all the things we should consider.

Line graphs are most useful when we want to track the change of something over time. Some things we could use a line graph for include:
rainfall over a period of time
the time the sun rises each day
the value of the Australian dollar compared to the US Dollar, over time
uses appropriate methods to collect data and constructs, interprets and evaluates data displays, including dot plots, line graphs and two-way tables
