- 1. Rotation of 180 degrees takes the point (x,y) to the point:
A) (x + 180, y) B) (-y, x) C) (y, x) D) (-y, -x) E) (-x,-y)
- 2. Rotation of 90 degrees counterclockwise about the origin takes the point (x, y) to the point:
A) (-y, x) B) (-x, -y) C) (y, -x) D) (-x, y)
- 3. THINK HARD: Reflection across the y-axis takes the point (x, y) to the point:
A) (x - 10, y - 10) B) (-x, y) C) (x, -y) D) (y, x)
- 4. If the point (2, 7) is translated using (x+4, y-10), where will it end up?
- 5. Find the slope between these 2 points: (2, -10) and (5, 9)

- 6. Find the perpendicular slope if the original slope is -6/11.
A) 1/16 B) 11/6 C) 6/11 D) -11/6
- 7. Solve for x please: 2/x = x/32
