Answer:
Explanation:
Follow the small parallel line closest to the x axis. When you reflect that line across the y axis. AB will be closest to the x axis still. What is going to make it further away when you cross the x axis? No reflection that is for sure. Answer A is not correct. Sorry.
B has exactly the same problem.
C is incorrect. Try it. AB will overlap A'B' when you complete the translation.
D I think you will find it is D. When you reflect it over the y axis, line AB is directly below A'B' So moving 7 units up makes the two lines coincide.
