document.write( "First thing, a line with an undefined slope is a vertical line.  That means that every point on the line has the same x-coordinate, and the y-coordinates are all of the real numbers.  I'm not sure what you meant by the - for the x-coordinate in the given ordered pair, but let's just say it stands for some real number a.  Then the x-intercept would be (a,0).  Since every point on the line must have an x-coordinate of a and we don't care what y is, the equation is simply <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=x=a ALIGN=MIDDLE  ALT=\"x=a\"   DISABLED_style= \"max-width:90%; height:auto;\" >  (and you can replace the a with whatever number you meant to put into your given ordered pair) </SPAN>\n" );
