\n" ); document.write( "If the line whose equation is  y = x + 2k  passes through point  (3, -5),  it means that the  x- and  y-coordinates of the point satisfy the given equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute the coordinates into the equation.  You will get\r
\n" ); document.write( "\n" ); document.write( "-5 = 3 + 2k.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It implies that  2k = -5 -3 = -8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence,  k = -4.\r
