You are looking for any vertical line with x value between -5 and +4.  Your description suggests you want the line to be perpendicular to the x axis.  It is not described any more clearly than that.  You can choose the midpoint if you want.   <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=x=k ALIGN=MIDDLE  ALT=\"x=k\"   DISABLED_style= \"max-width:90%; height:auto;\" > for any  <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=-5%3C=k%3C=4 ALIGN=MIDDLE  ALT=\"-5%3C=k%3C=4\"   DISABLED_style= \"max-width:90%; height:auto;\" >. </SPAN>\n" );
