Point P(-4, 1/2) and y = 1/2x - 4\r
\n" ); document.write( "\n" ); document.write( "Put x = -4 in the equation\r
\n" ); document.write( "\n" ); document.write( "y = 1/2 * (-4) -4 = -6
\n" ); document.write( "But y = 1/2 in point p
\n" ); document.write( "Therefore the point P is not on the graph
\n" ); document.write( "
