Can anyone help?!?! Because this question is so annoying because my coordinates are different from the options!

Answer:
B
Step-by-step explanation:
Since X is (7,11) and X' is (5,11) we are basically translating it 2 units to the left.
Do the same for Z.
Z's x coordinate is 8 and moving it to the left makes the x coordinate 6.
The y coordinate stays the same the Z' coordinates are (6,7).
If the new coordinates of x is (5,11) that means the whole triangle is translated 2 units to the left. This means that you have to shift point z 2 units to the left to get the new coordinates of z, and when that's done the coordinates of z' is B) (6,7)
