To show -3 - (-9), we can draw two arrows.
First, let's draw an arrow pointing to the left with a length of 3 units, representing -3.

Next, let's draw another arrow starting at the end of the first arrow, pointing to the left with a length of 9 units, representing -(-9).
<-- <---------
Finally, let's find the difference between the two arrows by subtracting the second arrow from the first arrow:
<-------------------
<-- <---------
The resulting arrow is pointing to the right with a length of 6 units. Thus, -3 - (-9) = 6.
