Answer :
Answer:
answer is b X,y to -X,-y
Explanation:
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
The answer will be B.
Remember the rules (clockwise):
90° = (x,y) -> (y,-x)
180° = (x,y) -> (-x,-y)
270° = (x,y) -> (-y,x)
Remember the rules (clockwise):
90° = (x,y) -> (y,-x)
180° = (x,y) -> (-x,-y)
270° = (x,y) -> (-y,x)
