Algebra.Com's Answer #810218 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! The slope of AB is 8/4 or 2 \n" ); document.write( "The slope of a perpendicular line to AB has slope which is the negative reciprocal of 2, or -1/2. \n" ); document.write( "That line goes through point (1, 1). \n" ); document.write( "Its equation is y-y1=m(x-x1) where m is slope and (x1, y1) point. \n" ); document.write( "y-1=-(1/2)(x-1) \n" ); document.write( "y=-(1/2)x+(3/2) \n" ); document.write( "- \n" ); document.write( "the other line using the point slope formula is y-6=2(x-5), or y=2x-4 \n" ); document.write( " |
