Answer 3

If you show YOUR work, you are more likely to get a quicker and more helpful response.

Start: (5,1) -- Quadrant 1
Reflect y ==> (-5,1) -- Quadrant II
Reflect x ==> (-5,-1) -- Quadrant III
Rotate 180º ==> (5,1) -- Quadrant I
Back where we started.

Just walk through it until you can get the Matrix Transformations more fluently. You'll see it soon enough.
