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.
Graphs have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. 1  The x-axis may contain categories or numbers.2  You read it from the bottom left of the graph.raphs have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. 1  The x-axis may contain categories or numbers.
