\n" ); document.write( "x1 y1 x2 y2
\n" ); document.write( "-2 -3 4 3
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 3 - -3 )/( 4 - -2 )
\n" ); document.write( "( 6 / 6 )
\n" ); document.write( "m= 1 \r
\n" ); document.write( "\n" ); document.write( "slope of line perpendicular to the line joining these two points will be -1 ( m1*m2-1)\r
\n" ); document.write( "\n" ); document.write( "m= -1
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point (1, -2) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "-2 = -1 + b
\n" ); document.write( "b= -2 - -1
\n" ); document.write( "b= -1
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = - x -1
