x1 y1 x2 y2

\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 0 - 2 )/( 4 - 0 )
\n" ); document.write( "( -2 / 4 )
\n" ); document.write( "m= - 1/2
\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 ( 0 , 2 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "2.00 = - 1/2 * 0 + b
\n" ); document.write( "2.00 = -0 + b
\n" ); document.write( "b= 2 + 0
\n" ); document.write( "b= 2
\n" ); document.write( "So the equation will be
