It's important to use multiple lines in a line graph so that you can identify each categories without confusion.
multiple lines may become confusing
The advantage is that you can compare multiple data sets in the same chart
a double line graph is a graph that is same as a line graph but there are two lines
You can compare two different data sets on the same chart.
By using multiple lines you can show multiple pieces of data; e.g. if you have a test for the heat of liquids, then you can show multiple different liquids on the same graph. Like water and oil, you can show the water as one line and the oil as another. Saving you the need to make more graphs and making data easier to compare.

Lines.
A line graph is most often used to show the passage of time, and shows the increase and decrease from one point to another. A multiple line graph is used to compare two sets of statistics.
A line graph.
No! Bar and line graphs are different bar graphs show bars and line graph shows lines.
Its called a line graph
For comparison purposes, a multiple line graph would be best.
