Algebra.Com's Answer #233223 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! perpendicular lines (or in this case, vectors) have slopes that are negative-reciprocals of each other\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the original slope is ___ (-13 - 3)/(-5 - 19) ___ or ___ -16 / -24 ___ or ___ 2/3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so the slope of the perpendicular is ___ -3/2 \n" ); document.write( " |
