(2,2)to(-2,2)" and "(6,-3)to(3,6)(2,2)(2,2) and (6,3)(3,6)

Explanation:

"Assuming a rotation about the origin"Assuming a rotation about the origin

"under a clockwise rotation about the origin of "(3pi)/2under a clockwise rotation about the origin of 3π2

• " a point "(x,y)to(-y,x) a point (x,y)(y,x)

rArr(2,2)to(-2,2)(2,2)(2,2)

rArr(6,-3)to(3,6)(6,3)(3,6)
