To simplify the expression [tex]\(-9 + 7\)[/tex], follow these steps:

1. Start with the expression: [tex]\(-9 + 7\)[/tex].
2. Identify the numbers involved: [tex]\(-9\)[/tex] and [tex]\(7\)[/tex].
3. Consider the signs of the numbers and perform the addition. Since [tex]\(-9\)[/tex] is a negative number and [tex]\(7\)[/tex] is a positive number, you are essentially subtracting [tex]\(7\)[/tex] from [tex]\(-9\)[/tex].
4. When you subtract [tex]\(7\)[/tex] from [tex]\(-9\)[/tex], you move [tex]\(7\)[/tex] units towards the positive side from [tex]\(-9\)[/tex].
5. Calculating this gives:

[tex]\[ -9 + 7 = -2 \][/tex]

Thus, the simplified expression is [tex]\(-2\)[/tex].

Therefore, the final result is [tex]\(-2\)[/tex]. So, the correct answer is:
[tex]\[ -2 \][/tex]
