Depends on the field you are working in.
Do you mean -a-bi, where a and b are real numbers? If so, then it would be -a+bi.
If a and b are complex numbers (non-real) numbers, then the conjugate cannot be given (in general) in a particular form.
But, if a and b are both real numbers, then -a-b is a real number and the conjugate of any real number is itself, thus the conjugate of -a-b would be -a-b.

Conjugate means that when you add both the numbers then there should be a rational number remaining. And also the product should also be a rational number.
In Surds:
Conjugate of a + vb is a - vb
In Complex Numbers :
Conjugate of a + ib is a - ib
So you should have an irrational number also. So you should mention that b is irrational or else your question will be wrong.
If b is irrational then the answer is -a + b is the conjugate of -a-b.
Hope you can understand this explanation.

The conjugate of -a-b is -a-b. The conjugate of a real number is that number.
But in case you meant -a-bi, then the conjugate is -a+bi; where i=sqrt(-1)

In general: if z= x + iy then x - iy is the conjugate.
For a reel the y = 0. So
The conjugate of -a-b is -a-b
