No it does not. Just take any two coordinates and try them both ways, the slope will be the same always.
\n" ); document.write( "For example (5, -1) and (3, 6)
\n" ); document.write( "m=(y - ysub1)/(x - xsub1)
\n" ); document.write( "(-1-6)/(5-3)=(-7)/2 or -(7/2)
\n" ); document.write( "(6-(-1))/(3-5)=7/(-2) or -(7/2)
\n" ); document.write( "Here it doesn't matter where the negative is, either in the numerator or the denominator, because both ways its show a negative slope \n" ); document.write( "

\n" );
