You can put this solution on YOUR website!
3X-Y=2 OR -Y=-3X+2 OR Y=3X-2 (RED LINE)
\n" ); document.write( "COORDINATES FOR THIS EQUATION ARE:
\n" ); document.write( "SET X=0 & SOLVE FOR Y.
\n" ); document.write( "Y=3*0-2
\n" ); document.write( "Y=-2 THUS THIS POINT IS (O,-2)
\n" ); document.write( "NOW SET Y=0 & SOLVE FOR X.
\n" ); document.write( "0=3X-2
\n" ); document.write( "3X=2
\n" ); document.write( "X=2/3 THUS THIS POINT IS (2/3,0).
\n" ); document.write( "X+Y=2 OR Y=-X+2 OR (GREEN LINE)
\n" ); document.write( "Y=-0+2
\n" ); document.write( "Y=2 THUS THIS POINT IS (0,2)
\n" ); document.write( "0=-X+2
\n" ); document.write( "-X=-2
\n" ); document.write( "X=2 THUS THIS POINT IS (2,0)
