+Now you have all the tools to create those wonderful dynamic, randomized problems that you've seen in 
+LON-CAPA. Consider a Numerical Response problem where the equations for two lines are randomly generated 
+and the students are asked to find the intercept. Try filling out your problem with the parameters shown 
+in Figure \ref{Slope Problem Parameters Figure}.. 
 
 When creating randomized problems, you want to make sure that the problems
-always have an answer. Consider what might happen if I had chosen the two
-slopes \emph{both} with the expression \texttt{\&random(-1.0,1.0,.2)}. One
+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.
