x1 y1 x2 y2
\n" ); document.write( "-3 -2 1 -2
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( -2 - -2 )/( 1 - -3 )
\n" ); document.write( "( 0 / 4 )
\n" ); document.write( "m= 0
\n" ); document.write( "The required line passes through both the points. So we select one point and plug it with the slope
\n" ); document.write( "Plug value of the slope and point ( -3 , -2 ) in
\n" ); document.write( "Y = m x + b OK
\n" ); document.write( "-2.00 = 0 * -3 + b
\n" ); document.write( "-2.00 = -0 + b
\n" ); document.write( "b= -2 + -2
\n" ); document.write( "b= 0
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = -2
