#### Answer

In order to graph an equation, plug in certain values for x, and then solve for the corresponding y values. This will create a table of coordinates for points on the graph you are creating. Then, plot all of the points on the graph, and connect them using a straight line. (While the line will not always be straight, this section only involves graphing straight lines.)

Here, only non-negative values are plotted.
