Answer: 1. D=(7, 4)
2. D=(-2, -2)
3. D=(6, -4)
Explanation:
1. point B goes to point C by moving right 6 units and moving down 2 units.
point A goes to point D by moving right 6 units and moving down 2 units.
A=(1, 6)
D=(1+6, 6-2)
D=(7, 4)
2. point B goes to point C by moving left 4 units and moving down 6 units.
point A goes to point D by moving left 4 units and moving down 6 units.
A=(2, 4)
D=(2-4, 4-6)
D=(-2, -2)
3. point B goes to point C by moving right 8 units and moving down 2 units.
point A goes to point D by moving right 8 units and moving down 2 units. A=(-2, -2)
D=(-2+8, -2-2)
D=(6, -4)
