2X-Y=4 -Y=-2X+4 Y=2X-4 (RED LINE)
\n" ); document.write( "2X-Y=6 -Y=-2X+6 Y=2X-6 (GREEN LINE)
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+2x+-4%2C+y+=+2x+-6%29+\" (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 2x -4 and y = 2x -6).
\n" ); document.write( "these 2 lines are paralllel thus there is no unique solution to these 2 equations.
