Question

ΔABC with vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise about the origin. It is then reflected across the line y = -x. What are the coordinates of the vertices of the image?

A'(0, 3), B'(2, 3), C'(1, 1)

A'(0, -3), B'(3, -2), C'(1, -1)

A'(-3, 0), B'(-3, 2), C'(-1, 1)

A'(0, -3), B'(-2, -3), C'(-1, -1)

Answer 1

Hope this helps!
Rotation of 90° clockwise: (x, y) → (y, −x)
Rotation of 90° counterclockwise: (x, y) → (−y, x)
Rotation of 180°: (x, y) → (−x, −y)
Across the line y = x
(x, y) → (y, x)
For you since x is negative it should probably be > (y, -x)
