Algebra.Com's Answer #312012 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! M(1,2) is the midpoint of line segment RS. If S has the coordinates (8,10), find the coordinates of R \n" ); document.write( "--- \n" ); document.write( "Let the coordinates of \"R\" be (x,y) \n" ); document.write( "---- \n" ); document.write( "(x+8)/2 = 1 \n" ); document.write( "(y+10)/2 = 2 \n" ); document.write( "---- \n" ); document.write( "x+8 = 2 \n" ); document.write( "y+10 = 4 \n" ); document.write( "--- \n" ); document.write( "x = -6 \n" ); document.write( "y = -6 \n" ); document.write( "--------------- \n" ); document.write( "Ans: R(-6.-6) \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
