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)
