Suppose a rectangle undergoes a reflection across the x-axis and a translation 5 units down. Which of the statements is true?

• The resulting rectangle will be congruent to the original rectangle regardless of the order of the rotation and the translation.
• The resulting rectangle will be congruent to the original rectangle only if the rotation occurs before the translation.
• The resulting rectangle will be congruent to the original rectangle only if the translation occurs before the rotation.
• The resulting rectangle will not be congruent to the original rectangle regardless of the order of the rotation and the translation.

Identify a sequence of transformations that will transform figure L into figure M.

• (x, y) → (-x, y), (x, y) → (x, -y), (x, y) → (x + 3, y)
• (x, y) → (-x, y), (x, y) → (x, -y), (x, y) → (x + 1, y)
• (x, y) → (-x, y), (x, y) → (x, -y), (x, y) → (x -4 , y)
• (x, y) → (-x, y), (x, -y) → (x, -y), (x, -y) → (x + 1, y)
