You can put this solution on YOUR website!
y=2x-2
\n" ); document.write( "y=x+2 subtract these equations
\n" ); document.write( "-----------------------
\n" ); document.write( "0=2x-x-2-2
\n" ); document.write( "0=x-4
\n" ); document.write( "x=4 answer.
\n" ); document.write( "y=2*4-2
\n" ); document.write( "y=8-2
\n" ); document.write( "y=6 answer. (4,6)
\n" ); document.write( "---------------------------------
\n" ); document.write( "solving graphically we get:
\n" ); document.write( "y=2x-2 (red Line)
\n" ); document.write( "y=x+2 (green line)
