Algebra.Com's Answer #533433 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The midpoint of AB \n" ); document.write( " ___ \n" ); document.write( " is M(4,2). If the coordinates of A are (6,4), \n" ); document.write( " what are the coordinates of B? \n" ); document.write( "========= \n" ); document.write( "Let the coordinates of \"B\" be (x,y):: \n" ); document.write( "Equations: \n" ); document.write( "(x + 6)/2 = 4 ; So x+6 = 8 ; So x = 2 \n" ); document.write( "---- \n" ); document.write( "(y+4)/2 = 2 ; So y+4 = 4 ; So y = 0 \n" ); document.write( "----- \n" ); document.write( "Ans: B = (2,0) \n" ); document.write( "================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------------ \n" ); document.write( " \n" ); document.write( " |
