Answer:

The last number line.

Step-by-step explanation:

To represent the sum of 8 + (-12), we need to represent 8 and -12 as follows:

Where 8 is represented with an arrow that goes to the right and -12 is represented with an arrow that goes to the left.

Then, if we will represent the sum of these numbers, the arrow of -12 should starts when the arrow of 8 ends. Therefore, the representation of 8 + (-12) is:

So, the answer is the last number line.
