Essentially, what you are doing is taking each individual point and moving that point as specified.
So, for example, problem 1 has coordinates as follows: (be aware: I have terrible eyesight, so the points are being named based on what I think the letters are).
X: located at (2,0), move 1 unit left, new location: (1,0) G: located at (4,0), move 1 unit left, new location: (3,0) Q: located at (2,-2), move 1 unit left, new location: (1,-2) C: located at (3,-4), move 1 unit left, new location: (2,-4)
