Answer key · Translate, reflect and rotate on a grid
1. (8, 4)
C is at (8, 1).
3 units up changes the up number: 1 + 3 = 4.
C′ is at (8, 4).
2. (3, 9)
C is at (9, 9).
6 units left changes the across number: 9 − 6 = 3.
C′ is at (3, 9).
3. (0, 5)
C is at (0, 0).
5 units up changes the up number: 0 + 5 = 5.
C′ is at (0, 5).
4. (5, 1)
A is at (2, 1).
3 units right changes the across number: 2 + 3 = 5.
A′ is at (5, 1).
5. (3, 8)
A is at (5, 8).
2 units left changes the across number: 5 − 2 = 3.
A′ is at (3, 8).
