1.  What is the reflection image of (5, -3) across the line y = -x?
A.
B.
C.
D.
2.  The same hemisphere of the moon always faces Earth.  Thus, the motion of the moon about Earth for a given time interval can be modeled by a rotation.  The center of the rotation is the center of the Earth.  The angle of rotation is determined by the time interval, given that one journey of the moon around Earth takes about 27 1/3 days.In how many days does the moon complete a 90º angle of rotation?
A.
B.
C.
D.

A.
B.
C.
D.

10.  The same hemisphere of the moon always faces Earth.  Thus, the motion of the moon about Earth for a given time interval can be modeled by a rotation.  The center of the rotation is the center of the Earth.  The angle of rotation is determined by the time interval, given that one journey of the moon around Earth takes about 27 1/3 days.What rotation is modeled by the motion of the moon?
A.
B.
C.
D.
