Answer:
7
Step-by-step explanation:
The distance between -9 and -2 on a number line is 7. If you check the picture attached, you will find that there are 7 units between -9 and -2.
Another way to calculate this is by subtracting the two numbers (In any order) and then taking the absolute value of the number. Therefore:
-9 - (-2) = -7
Abs(-7) = 7
Also it could be:
-2 - (-9) = 7
Abs(7) = 7
