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.
However, we've probably been doing so on charts that look like this: But since we're blasting ahead in math, we'll soon be graphing on charts that look like this: This is called a Cartesian coordinate graph. It's made up of two axes (axes is just the plural of axis): The horizontal axis is called the x-axis. And the vertical one is the y-axis. When the two axes meet, they form four quadrants.
