Reflect shapes in lines such as x = 2 or y = 1
Line x=2 would be the mirror line.
When reflecting, a point, A = (3,2), count the distance from this point to the mirror line (you might need a graph paper)
(3,2) is 1 point from the line x=2
count one point in the opposite direction of the mirror line (the Y value is not changed). The resulting point would be A' = (1,2). Do the same for any other points in the shape you are reflecting, then connect them to show the shape.

The same is applicable for any other line such as y=1, x=2, y=2, etc.
