\n" ); document.write( "x1 y1 x2 y2
\n" ); document.write( "-1 -3 4 1
\n" ); document.write( "
\n" ); document.write( "slope m = (y2-y1)/(x2-x1)
\n" ); document.write( "( 1 - -3 )/( 4 - -1 )
\n" ); document.write( "( 4 / 5 )
\n" ); document.write( "m= 4/5
\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 ( -1 , -3 ) in
\n" ); document.write( "Y = m x + b
\n" ); document.write( "-3.00 = 4/5 * -1 + b
\n" ); document.write( "-3.00 = - 4/5 + b
\n" ); document.write( "b= -3 + 4/5
\n" ); document.write( "b= -2 1/ 5
\n" ); document.write( "So the equation will be
\n" ); document.write( "Y = 4/5 x -11/5
