Answer 2

Rule: Rotate any point (x,y) 180 degrees and it will land on (-x,-y)

example: take (2,1) and rotate it 180 degrees. it will become (-2,-1)

Answer 3

Side note: if P is the original point, and Q is the new point after you rotate the point 180 degrees around the origin, then the line PQ will go through the origin (0,0)

Answer 4

Thank you! So it would be (1,-1), (-2, 4), and (-4, -2)?

Answer 5

(2,4) becomes (-2,-4)

Answer 6

** (-2, -4)

Answer 7

Answer 8
