Well, for A, try thinking how a the shape would end up in that position. Obviously it needs a rotation. Around where? Does it also need a translation?

narissa · Answer

Rotation around the x-axis I think it might need a translation as well but I'm not good at this kind of geometry.

sapphiremoon · Answer

Well, generally we rotate around points and reflect across axes. But I agree that it should be rotated around the origin. But a 90 degree rotation, while it orients the figure properly, leaves the top corner at (-3, -1) instead of (-1, -1) So we also need a translation.

That all right? What about b? How do I do that?

narissa · Answer

That is all right*

sapphiremoon · Answer

I don't really know what that sentence means, but we did agree on a 90 degree counterclockwise rotation about the origin (0, 0) and a translation to the right from (-3, -1) to (-1, -1).
