So this figure has a vertical center. What is it?

OpenStudy (anonymous):

For a 180-flip it is simple, Just switch both of the signs, i.e. (x, y)-->(-x, -y) So, the answer is (2, -4)

OpenStudy (anonymous):

It's going to rotate around the center at (-2,1) so it will end up at (-2,-2)

OpenStudy (anonymous):

You don't switch x, since it's on a vertical line through the center, x is unchanged.
