okay well here is my problem i need help on these question and how to do them, these are the direction;
\n" ); document.write( "given the coordinate of one endpoint of AB [straight line on top of the AB] and its midpoint M, find the coordinate of the other endpoints (x,y)
\n" ); document.write( "#1 A(0,9) M(2,5)
\n" ); document.write( "(x+0)/2 = 2 : x = 4
\n" ); document.write( "(y+9)/2 = 5 : y = 1
\n" ); document.write( "------------------------------
\n" ); document.write( "#2 B(-5,1) M (1,-1)
\n" ); document.write( "(-5+x)/2 = 1 ; x = 7
\n" ); document.write( "(1+y)/2 = -1 ; y = -3
\n" ); document.write( "-------------------------------
\n" ); document.write( "#3 A(-2,3) M(0.5,0.5)
\n" ); document.write( "(-2+x)/2 = 0.5 ; x = 3
\n" ); document.write( "(3+y)/2 = 0.5 ; y= -2
\n" ); document.write( "-------------------------------
\n" ); document.write( "#4 A (4,2) M (-2,10)
\n" ); document.write( "(x+4)/2 = -2 ; x = -8
\n" ); document.write( "(y+2)/2 = 10 ; y = 18
\n" ); document.write( "-------------------------------
