Any line parallel to the given line
\n" ); document.write( "will have the same slope
\n" ); document.write( "-------------------------
\n" ); document.write( "slope = [ change in y ] / [ change in x ]
\n" ); document.write( "slope = \"+%28+7+-+3+%29+%2F+%28+-4+-%28-4%29+%29+\"
\n" ); document.write( "slope = \"+4+%2F+0+\"
\n" ); document.write( "Any number divided by \"+0+\" is infinity,
\n" ); document.write( "so the slope of this line is infinite
\n" ); document.write( "and any line parallel to this line has
\n" ); document.write( "infinite slope
\n" ); document.write( "
\n" ); document.write( "
