A triangle has vertices at [tex]\( L(2, 2) \)[/tex], [tex]\( M(4, 4) \)[/tex], and [tex]\( N(1, 6) \)[/tex]. The triangle is transformed according to the rule [tex]\( R_0 \)[/tex], [tex]\( 180^{\circ} \)[/tex].

Which statements are true regarding the transformation? Select three options.

A. The rule for the transformation is [tex]\((x, y) \rightarrow (-x, -y)\)[/tex].

B. The coordinates of [tex]\( L' \)[/tex] are [tex]\((-2, -2)\)[/tex].

C. The coordinates of [tex]\( M' \)[/tex] are [tex]\((-4, 4)\)[/tex].

D. The coordinates of [tex]\( N' \)[/tex] are [tex]\((6, -1)\)[/tex].

E. The coordinates of [tex]\( N' \)[/tex] are [tex]\((-1, -6)\)[/tex].

To solve this problem, we need to apply the transformation rule [tex]\( (x, y) \rightarrow (-x, -y) \)[/tex] to each vertex of the triangle and verify the new coordinates.

### Step-by-step Transformation:

1. Transforming [tex]\( L(2, 2) \)[/tex]:
- Apply the rule:
[tex]\[ L' = (-2, -2) \][/tex]

2. Transforming [tex]\( M(4, 4) \)[/tex]:
- Apply the rule:
[tex]\[ M' = (-4, -4) \][/tex]

3. Transforming [tex]\( N(1, 6) \)[/tex]:
- Apply the rule:
[tex]\[ N' = (-1, -6) \][/tex]

Now, we check the provided options against these transformed coordinates:

1. The rule for the transformation is [tex]\( (x, y) \rightarrow (-x, -y) \)[/tex].
- True. This is the given rule for a 180-degree rotation.

2. The coordinates of [tex]\( L' \)[/tex] are [tex]\( (-2, -2) \)[/tex].
- True. [tex]\( L' \)[/tex] was transformed from [tex]\( L(2, 2) \)[/tex] to [tex]\( (-2, -2) \)[/tex].

3. The coordinates of [tex]\( M' \)[/tex] are [tex]\( (-4, 4) \)[/tex].
- False. The correct coordinates of [tex]\( M' \)[/tex] are [tex]\( (-4, -4) \)[/tex].

4. The coordinates of [tex]\( N' \)[/tex] are [tex]\( (6, -1) \)[/tex].
- False. The correct coordinates of [tex]\( N' \)[/tex] are [tex]\( (-1, -6) \)[/tex].

5. The coordinates of [tex]\( N' \)[/tex] are [tex]\( (-1, -6) \)[/tex].
- True. This matches the transformed coordinates of [tex]\( N \)[/tex].

Therefore, the three true statements regarding the transformation are:

1. The rule for the transformation is [tex]\( (x, y) \rightarrow (-x, -y) \)[/tex].
2. The coordinates of [tex]\( L' \)[/tex] are [tex]\( (-2, -2) \)[/tex].
5. The coordinates of [tex]\( N' \)[/tex] are [tex]\( (-1, -6) \)[/tex].

So, the correct answers are:
- The rule for the transformation is [tex]\((x, y) \rightarrow (-x, -y)\)[/tex].
- The coordinates of [tex]\(L '\)[/tex] are [tex]\((-2, -2)\)[/tex].
- The coordinates of [tex]\(N '\)[/tex] are [tex]\((-1, -6)\)[/tex].
