Which number line best shows how to solve −6 − (−8)? 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 6. Another arrow points from negative 6 to 2. 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 6.

Answer=A number line from negative 10 to 10 is shown, with numbers labeled at intervals of 2 Remember that subtracting a negative number is the same as adding a positive number, so... -6-(-8)=-6+8 -6+8=2 Since the answer, 2, and the addends, -6 and 8 fall in between -10 and 10. The number line will suit the problem. They are also all even numbers so if the labels are in intervals of 2, it will be easily read.
