- 1. Rotation of 180 degrees takes the point (x,y) to the point:
A) (-y, -x) B) (-x,-y) C) (-y, x) D) (x + 180, y) E) (y, x)
- 2. Rotation of 90 degrees counterclockwise about the origin takes the point (x, y) to the point:
A) (y, -x) B) (-y, x) C) (-x, y) D) (-x, -y)
- 3. THINK HARD: Reflection across the y-axis takes the point (x, y) to the point:
A) (y, x) B) (x, -y) C) (-x, y) D) (x - 10, y - 10)
- 4. If the point (2, 7) is translated using (x+4, y-10), where will it end up?
