Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative.

A single point is rounded off to avoid a pointed turn. A table of values is used to find the points to plot for a graph. A row is used for each term in the equation to work out the coordinates.
