Which algebraic rule describes the 180° counterclockwise rotation about the origin

• choixongdong: rule describes the 180° counterclockwise rotation about the origin=
  (x,y)→(−x,−y)
  
• ApusApus:

  Answer:

  [tex](x,y)\rightarrow (-x,-y)[/tex]

  Step-by-step explanation:

  We are asked to find the the algebraic rule describes the 180° counterclockwise rotation about the origin .

  We know that when we rotate a point 180° counterclockwise rotation about the origin , the x and y-coordinates change their sign.

  [tex](x,y)\rightarrow (-x,-y)[/tex]

  Therefore, our required rule is [tex](x,y)\rightarrow (-x,-y)[/tex].
