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.You can test your understanding by doing the activity on the menu bar (on top).
