document.write( "Note: easiest points to find is when x = 0  or y = 0
\n" );
document.write( " 3x+ y = 2,  2 Pts(x,y) on this line (0,2) and (2/3, 0) Green Line
\n" );
document.write( " y = 2x-2,   2 Pts(x,y) on this line (0,-2) and (1, 0)  Blue Line

document.write( "substituting  y  =( 2x-2) also works:
