The three (3) kinds of graphs are (1) and (3). (2) are used to organize data that is too detailed or complicated to be describe adequately in the text, allowing the reader to quickly see the result.
Line graphs simply use a line to connect the data points that you plot. They are most useful for showing trends and for identifying whether two variables relate to (or "correlate with") one another.
Examples of trend data include how sales figures vary from month to month, and how engine performance changes as the engine temperature rises.
You can use correlation data to answer questions like, "On average, how much sleep do people get, based on their age?" or "Does the distance a child lives from school affect how frequently they are late?"
