\n" ); document.write( "\n" ); document.write( "We know that parallel lines have equal slopes and perpendicular lines have slopes that are negative reciprocals. Put both of your equations into slope intercept form. Then by inspection of the coefficient on

in each equation determine the slope,

then the lines are parallel.\r

where

, then the lines are perpendicular. Or if one of the slopes is zero and the other is undefined, then the lines are also perpendicular.\r
