Answer:
1. c; 2. a; 3. b
Step-by-step explanation:
A(3,-1) translated to (3-4, -1+1)=(-1,0); then reflecting to x=1 (in this case, y doesn't change, and only x value change. x=-1 is 2 unit left side of x=1 line, so new reflected x value would be 2 unit right side of x=1 line, which is 3) gives (3,0).
B(7,1) --> (3,2) --> (-1,2)
C(5,-4) --> (1,-3)--> (1,-3)
