Answer:
1. b
2. b
3. R' is (-2,0)
E'(2,-2)
F'(4,-4)
Explanation:
B has two lines of symmetry.
The second picture ooption is b. If you reflect a point across the x axis, just negative the y coordinate.
The third picture
Since R lies on the x axis, it stays the same so
R' is (-2,0)
To reflect E about the x axis, just negate the y variable so we get
E'(2,-2)
To reflect F about the x axis, negate the y variable and we get
F'(4,-4)
