The solution set, a set of ordered pairs of the form such that the coordinate values make the given equation a true statement, has infinite elements.
Pick any real number value you like for . Substitute this value in place of in the equation. Solve the equation for . Form an ordered pair, . Plot the point.
Repeat the above process with a different value for .
Draw a line through the two points, extending to the limits of your graph.
The graph is a partial representation of the solution set of the equation. It is only a partial representation because the line extends on both ends over all of the values in the interval
