The midpoint of qr is (1,-2) one endpoint is r(4,-5) find the coordinates of the other endpoint
\n" ); document.write( "----------
\n" ); document.write( "Get the x and y differences:
\n" ); document.write( "diffx = 4-1 = 3
\n" ); document.write( "diffy = -5 -(-2) = -3
\n" ); document.write( "---
\n" ); document.write( "Subtract the differences from the midpoint:
\n" ); document.write( "x: 1-3 = -2
\n" ); document.write( "y: -2 + 3 = 1
\n" ); document.write( "--> (-2,1)
\n" ); document.write( " \n" ); document.write( "
