  • The reflection of the point (x, y) across the x-axis is the point (x, −y) = P(x, y) → P'(x, y)
    • _x000D_
  • The reflection of the point (x, y) across the y-axis is the point (−x, y) = P(x, y) → P'(−x, y)
    • _x000D_
  • The reflection of the point (x, y) across the line y = x is the point (y, x) = P(x, y) → P'(y, x)
    • _x000D_
  • The reflection of the point (x, y) across the line y = −x is the point (−y, −x) = P(x, y) → P'(−y, −x)
