Original triangle a- 1,1 b- 2,3 c- 4,3

A) Reflection in y axis

B) Reflection in the line y= -1

C) Reflection y=2x

Now I think the first one would be A- -1,1 B- -2,3 C- -4,3.

The second I believe to be A- 1, -3 B-2, -5 C- 4, -5.

The third can someone please help.

Can you please tell me if the first two are correct and what the third is. Thanks
