# Question:MapleTA graphing algorithm

## Question:MapleTA graphing algorithm

Hi all,

I am attempting to construct a randomized questions using algorithms and the sketch question type.

I have defined my variables algorithmically.  The sketch question type only allows a static answer, and hence I am trying to modify the code.

As you can see below the code (part.1.answer...) is looking for points located at (7,0) and (0,-7).  I would like to replace the 7 with variable \$xint and -7 with variable \$yint, but it seems the @-symbols are some form of termination point that won't allow variables to carry-into the expression.

Looking for ideas??  I do not want to change to multiple choice.

Thanks,
