The graph of a relation of the form y = 5 is a line parallel to the x-axis because the y value never changes. A line parallel to the x-axis is called a horizontal line. The graph of a relation of the form x = 5 is a line parallel to the y-axis because the x value never changes. A line parallel to the y-axis is called a vertical line. Plot the graph of each of the following relations: horizontal line, vertical line.
When you plot a graph of your data, the x-axis is the independent variable and the y-axis is the dependent variable. In our example, the height of the plant would be recorded on the y-axis while the substance used to water the plants would be recorded on the x-axis.
