1) x-y=1
\n" ); document.write( "-Y=-X+1
\n" ); document.write( "Y=X-1 (RED LINE)
\n" ); document.write( "3x+y=7
\n" ); document.write( "Y=-3X+7 (GREEN LINE)
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+x+-1%2C+-3x+%2B7%29+\" (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions x -1 and -3x +7).
\n" ); document.write( "ANSWER (2,1)
\n" ); document.write( "2) 2x-y=1
\n" ); document.write( "-y=-2x+1
\n" ); document.write( "y=2x-1 (red line)
\n" ); document.write( "3y=6x-3
