The best number line that shows how to solve −4 − (−6) would be the third option: A number line from negative 10 to 10 is shown, with numbers labeled at intervals of 2. An arrow is shown from point 0 to negative 4. Another arrow points from negative 4 to negative 2.
This number line accurately represents subtracting a negative number from a negative number which results in a positive number. Starting at 0, we move to the left 4 units to -4, and then we continue to move to the left 2 units to reach -6, which is the result of the subtraction.
