What does the algebraic representation shown below represent?

(x, y) -> (-x, y)

• Each point of a figure will be reflected across the y-axis.

• Each point of a figure will be reflected across the x-axis.

• Each point of a figure will be rotated $90\degree$ clockwise.

• Each point of a figure will be rotated $90\degree$ counterclockwise.

• (x,y) -> (x + 4.5, y - 10)

• (x,y) -> (x + 10, y - 4.5)
