Graphing Using Intercepts
To graph the equation using the intercept method, first determine the intercepts. Finding the x-intercept and the y-intercept both result in the origin point . Since a straight line requires more than a single point to graph correctly, select two additional values for to generate more solution points. For example, substituting produces , resulting in the ordered pair . Substituting produces , providing the ordered pair . Plot the three coordinate points , , and on a Cartesian plane, confirm they fall on a uniform line, and connect them to finish the graph.
