The minus sign in front of the means
that the line slopes from the upper left to
the lower right. Here's a plot:
--------------------
The negative slope means that as the number of games, ,
increases, the number of minutes remaining decreases.
--------------------
At the x-intercept, the number of minutes remaining is zero,
so all the games, , have been played, and
the tournament is over.
Note that , no minutes remaining.
