2. Parts of a line graph

The x-axis is also known as the independent axis because its values do not depend on anything.

The y-axis is also known as the dependent axis because its values depend on variables on the x-axis.

Each of these axes is labeled in a type of data, for example, the x-axis is labeled as weeks, months, time etc. and the y-axis is labeled as dollars, velocity or the quantity of the item.

The data points are marked on the chart according to the x-axis and y-axis which are joined by a line in a dot-to-dot pattern.

The table on the right shows the different parts of a line graph.
