Michael,

Thanks. I went with Ross's strategy:

% Exercise #7
\begin{exercise}\label{ex:4-1-7}
\hspace{.5cm}\lower0.65\baselineskip\hbox{$\begin{aligned}
3x-3y&=12\\
x-y&=-3
\end{aligned}$}

I was able to use our perl code section to do something like this, where the second equation has the form y=slope2 * x+b.

my $howmuch=isinteger($slope2) ? "0.65" : "1.0";

Then code our question like this:

\shortqu=\hspace{.5cm}\lower#howmuch\baselineskip\hbox{$\begin{aligned}
#eqn1&=#C\\
y&=#eqn2
\end{aligned}$}
|@|

The result is not bad. See exercises 7-18 on page 4 of:

Thanks for your help.

David.
