1.4x-2y=-6
\n" ); document.write( "2.2x-y=-3
\n" ); document.write( "First graph equation 1.
\n" ); document.write( "When x=0, -2y=-6, y=3.
\n" ); document.write( "When y=0, 4x=-6, x=-3/2
\n" ); document.write( "
\n" ); document.write( "Next, equation 2.
\n" ); document.write( "2.2x-y=-3
\n" ); document.write( "When x=0, -y=-3, y=3.
\n" ); document.write( "When y=0, 2x=-3, x=-3/2.
\n" ); document.write( "As you see the x and y intercepts are the same for equations 1 and 2.
\n" ); document.write( "Equations 1 and 2 are the same equation.
\n" ); document.write( "If you multiply equation 2 by (2), you get equation 1.
\n" ); document.write( "They have infinitely many solutions.
\n" ); document.write( " \n" ); document.write( "
\n" );
