2. Simplify the following fraction:
*
23
4

The distance should be two units.

Step-by-step explanation:

Looking at the correlation [after knowing it's a rectangle] between point(s) A and D, they both have opposite X's. And that tells me that B and C have to be opposite as well to match a rectangle.

Therefore, C should be 3,-2, since it's B's opposite Y.

Hopefully this makes sense and you get this question correct! :)
