After a reflection over the x-axis 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 x-axis 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
