Answer 1

Answer:

• C)  (x, y) ⇒ (-x, y)
• D)  (x, y) ⇒ (x, y+4)

Step-by-step explanation:

ΔDEF is a reflection and translation of ΔABC.

You know it is a reflection because the corresponding vertices have opposite orientations: CCW vs. CW. You know it is a horizontal reflection because the line EF corresponding to vertical line BC is still vertical.

You know a vertical translation is involved because corresponding vertices are all offset vertically from each other by the same amount (4 units).
