x1 y1 x2 y2
\n" ); document.write( "-4 -8 8 4
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 4 - -8 )/( 8 - -4 )
\n" ); document.write( "( 12 / 12 )
\n" ); document.write( "m= 1
\n" ); document.write( "
\n" ); document.write( "Plug value of the slope and point ( -4 , -8 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "-8.00 = -4 + b
\n" ); document.write( "b= -8 - -4
\n" ); document.write( "b= -4
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = x -4
\n" ); document.write( " \n" ); document.write( "
