Graphing by Plotting Points
To graph the equation , recognize that it contains only one variable, meaning the -value is always the constant regardless of the -value. By creating a table of values where the -coordinate is always and selecting arbitrary values for the -coordinates (such as , , and ), we obtain ordered pairs like , , and . Plotting these ordered pairs on a coordinate plane and connecting them produces a vertical line that passes through the -axis at .
