You can put this solution on YOUR website!
That should be right. Your line should be a perpendicular bisector to the segment formed by the two points.
\n" ); document.write( "m = (4 - 2) / (-1 - 5) = -1 / 3
\n" ); document.write( "Perpendicular slope = 3
\n" ); document.write( "w/ point ( (-1 + 5)/2 , (4 + 2)/2 ) or ( 2 , 3 )
\n" ); document.write( "y - y1 = m(x - x1)
\n" ); document.write( "y - 3 = 3(x - 2)
\n" ); document.write( "y - 3 = 3x - 6
\n" ); document.write( "y = 3x - 3
\n" ); document.write( "
\n" );
