Just pick any value of x you want and substitute it into the equation to solve for y.  Do that again to get a second ordered pair, plot both of your points (ordered pairs), and connect with a straight line.  The graph is: <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cx-1%29 ALIGN=MIDDLE  ALT=\"graph%28300%2C300%2C-5%2C5%2C-5%2C5%2Cx-1%29\"   DISABLED_style= \"max-width:90%; height:auto;\" > </SPAN>\n" );
