Math Exam Resources/Courses/MATH152/April 2016/Question A 14

Hey, Thanks for your detailed solution to this question. Yes, I understand it perfectly. But I have made some changes to your solution. I think it would be better if we just fix one point ( say (2,-2) in this case), then calculate the two vectors pointed out from this point. (4,3)-(2,-2)=(2,5), (3,1)-(2,-2)=(1,3). In this way, we no longer need to take the absolute value of the determinant. If you disagree with my changes or have any further questions, feel free to message me:)

The new solution looks good. Thanks for the revision.
