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.
Each point on this graph represents an ordered pair of data: for each value of Z there is a corresponding value of V. Each value of Z is plotted along the horizontal axis, also called the x axis or abscissa, and the corresponding value of V is plotted along the vertical axis, also called the y axis or ordinate.
