Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)
A 180 degree rotation around the origin flips the signs of x and y, so you get:
(2, 8) (6, 8) (11, 1) (7, 3)
Then a translation to the left 6 units just subtracts 6 from all the x values:
(-4, 8) (0, 8) (5, 1) (1, 3)
Those are your points! Hope this helped!
