1. **Problem statement:**
Draw the image of triangle A after (i) a reflection in the line $y = -x$ and (ii) a translation by the vector $(-2, -9)$.
2. **Reflection in the line $y = -x$:**
The rule for reflecting a point $(x, y)$ in the line $y = -x$ is to swap and negate the coordinates: $(x, y) \to (-y, -x)$.
3. **Vertices of triangle A:**
Given approximately as $(1, 2)$, $(4, 2)$, and $(1, 7)$.
4. **Apply reflection to each vertex:**
- $(1, 2) \to (-2, -1)$
- $(4, 2) \to (-2, -4)$
- $(1, 7) \to (-7, -1)$
5. **Translation by vector $(-2, -9)$:**
The rule for translation is to add the vector components to each vertex: $(x, y) \to (x - 2, y - 9)$.
6. **Apply translation to original vertices of triangle A:**
- $(1, 2) \to (1 - 2, 2 - 9) = (-1, -7)$
- $(4, 2) \to (4 - 2, 2 - 9) = (2, -7)$
- $(1, 7) \to (1 - 2, 7 - 9) = (-1, -2)$
**Final answers:**
- Reflected triangle vertices: $(-2, -1)$, $(-2, -4)$, $(-7, -1)$
- Translated triangle vertices: $(-1, -7)$, $(2, -7)$, $(-1, -2)$
