If a figure is translated 5 units to the right and 3 units up, what is the rule for this transformation?
(x, y) → (x + 5, y + 3)
(x, y) → (x - 5, y - 3)
(x, y) → (x + 3, y + 5)
(x, y) → (x - 3, y - 5)

Describe the sequence of transformations that maps triangle ABC to triangle A'B'C' if A'B'C' is a reflection of ABC over the x-axis followed by a translation 3 units up.
Reflect over the x-axis, then translate (x, y) → (x, -y) → (x, -y +3)
Reflect over the y-axis, then translate (x, y) → (-x, y) → (-x, y +3)
Reflect over the x-axis, then translate (x, y) → (x, -y)→ (x, -y -3)
Reflect over the y-axis, then translate (x, y) → (-x, y)→ (x, -y-3)
