My teenage daughter's math teacher has posed a riddle to her class:  why is the 
letter "m" traditionally used (at least here in the US, I don't know about 
elsehwere) to indicate the slope of a line on a graph?  Is there some 
underlyinig meaning, or a historical convention?
Thanks for any insights
