Final answer:
Line graphs, pie graphs, and bar graphs are three kinds of graphs that can be used to represent data in different ways.
Step-by-step explanation:
There are three kinds of graphs that can be used to represent data: line graphs, pie graphs, and bar graphs.
A line graph is most appropriate when showing the relationship between two variables, with one variable on the horizontal axis and the other on the vertical axis.
A pie graph is best used to show how something is allotted, such as a sum of money or a group of people. Lastly, a bar graph is useful for showing relationships between entities, where each bar represents a certain entity.
