You can put this solution on YOUR website!
Convert the lines to slope intercept form, $\"y=mx%2Bb\"$ .
\n" ); document.write( "Then compare slopes.
\n" ); document.write( "Parallel lines have identical slopes, $\"m1=m2\"$
\n" ); document.write( "Perpendicular lines have slopes that are negative reciprocals, $\"m1%2Am2=-1\"$ .
\n" ); document.write( "All others fall into the neither category.
