You can put this solution on YOUR website!
1) One, None, or infinitely many
\n" ); document.write( "2) One--two lines intersect each other at one point only
\n" ); document.write( " None--two lines are parallel to each other (they have the same slope/rate of change)
\n" ); document.write( " Infinitely Many--two lines intersect each other at all points (one line lies right on top of the other)
\n" ); document.write( "3) One
\n" ); document.write( "y-3x=7
\n" ); document.write( "3y+x=-8\r
\n" ); document.write( "\n" ); document.write( "none
\n" ); document.write( "y-3x=7
\n" ); document.write( "y-3x=-10\r
\n" ); document.write( "\n" ); document.write( "infinitely many
\n" ); document.write( "y-3x=7
\n" ); document.write( "2y-6x=14
\n" ); document.write( "
\n" );
