Line graphs compare two variables. Each variable is plotted along an axis . A line graph has a vertical axis and a horizontal axis. So, for example, if you wanted to graph the height of a ball after you have thrown it, you could put time along the horizontal, or x-axis, and height along the vertical, or y-axis.
As I mentioned before, each type of graph has characteristics that make it useful in certain situations. Some of the strengths of line graphs are that:
They are good at showing specific values of data, meaning that given one variable the other can easily be determined.
They show trends in data clearly, meaning that they visibly show how one variable is affected by the other as it increases or decreases.
They enable the viewer to make predictions about the results of data not yet recorded.
