Answer:
A (-2,8) B (-1,5) C (-6,2)
A(-2,-7) B(-5,-8) C(-8,-3)
Explanation:
x,y x,y x,y
A(7,-2) , B(8,-5) , C(3,-8)
translation (7-9),(-2+10) (8-9),(-5+10) ( 3-9),(-8+10)
(x-9) and (y+10) (-2,8) (-1,5) (-6,2)
when rotation 270 degrees counterclockwise around the origin:
A(x,y ) Then A'(-y,x) means switch x and y and make x negative
A(7,-2 ) rotation 270 degrees counterclockwise (-2,-7)
B(8,-5) to (-5,-8)
C(3,-8) to (-8,-3)
