reflection in the x-axis just takes
(x,y) -> (x,-y)
so, just change the sign of all the y-coordinates.
(x,y) -> (x,-y)
so, just change the sign of all the y-coordinates.

Steve, is it??
A(1,4) -> A'(1,-4)
B(3,-2) -> B'(3,2)
C(4,1) -> C'(4,-2)
A(1,4) -> A'(1,-4)
B(3,-2) -> B'(3,2)
C(4,1) -> C'(4,-2)
