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