After a reflection over the xaxis I have to find the coordinates of A1, B1, C1
I am having trouble with b1.
A(1,4) B(3,2) C(4,2)
The reflection should be:
A1 should be (1,4)
B1 ??????
C1 should be (4,2)
Can younhelp with the b1 coordinates and check my other coordinates too?

Imagine the xaxis as an axle, so anything above will got below, and anything below will go above,
so for B
(3,2) >(3 , 2)
the other two are correct
