+always have an answer. Consider what might happen if two
+slopes are chosen, \emph{both} with the expression \texttt{\&random(-1.0,1.0,.2)}. One
out of ten students would get a problem where both slopes were equal, which
has either no solution (for unequal y-intercepts) or an infinite number of
solutions (for equal slopes and y-intercepts). Both of these cause a division-by-zero
error on the division that computes the answer. There are many ways to avoid
this, one of the easiest of which is picking one slope negative and one positive.
-This same problem can show up in many other places, too, so be careful.
