First of all, x =-1 (y don’t change) so first 2 answer is out.
Now mirror to x-1 >>>
A(0,-1)
0 >> -1 is left one step so -1 left one step is -2
A(0,-1) >> A’(-2,-1)
A(-5,0)
-5 >> -1 is right 4 step so -1 right 4 step is 3
A’(3,0)
This is correct
Answer is D

If you don't know the value of 'a', we can only simplify.
4a - 11a = -7a
We combine since they are like terms.
