Answer:
- B. Reflection across the Y axis.
Explanation:
Translations on the coordinate plane has different coordinates of the shape, and reflect.
Reflections on coordinate plane have the same coordinates, they are just in different quadrants.
As you can see, the coordinates of the first triangle on the left is (-6, -2), (-2, -4), and (-4, -6).
On the right triangle, the coordinates are (6, -2), (2, -4), and (4, -6).
Your answer is B.
