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.
3. Click Scatter with Straight Lines. Note: also see the subtype Scatter with Smooth Lines. Result: Note: we added a horizontal and vertical axis title. The horizontal axis of a scatter chart is a value axis, so you have more axis scaling options (the same as a vertical axis which always is a value axis).
