Answer 1

When you do a 270 degree rotation counterclockwise, the values change according to the following:

(x,y) -> (y,-x)

So for the points given

(0,1) -> (1,0)

(2,1) -> (1,-2)

(3,5) -> (5,-3)

(-1,5) -> (5,1)

Her answers are not correct. It seems like she took the negative sign for the wrong term.
