The problem asks which number line correctly represents $-6 + 2$.

Step-by-step solution:

1. Start at $-6$ on the number line.
2. Since we are adding $+2$, move 2 steps to the right.
3. This should end at $-4$.

Now, looking at the options in the image:

• The first number line (selected option) starts at $-6$ and moves right by 2 steps to $-4$, which is correct.

Thus, the first option is the correct answer.
