In Section 1 of the January 1997 test, I'm having some trouble with question # 17. This question involves the number of diagonals with a positive slope within a pentagon placed in a coordinate plane. I believe that the answer is C:2, because the two diagonals AC and AD both have a positive slope. However, the answer is B:1. Perhaps I don't truly know the definition of a diagonal? Anyway, please help me if you can. I normally do very well on SAT math and it irritates me when I can't understand a question. Thanks guys!

The answer is C, according to the book. You are right, my friend.

The answer should be C. In the pentagon, only two lines with a positive slope can be drawn, from A to C, and from A to D.

Where did you see the answer listed as B? It is C, for sure, for sure :)
