Final answer:
The distance between -172 and -69 on a number line is 103 units.
Step-by-step explanation:
The distance between -172 and -69 on a number line can be found by subtracting one number from the other. In this case, -69 is to the right of -172 on the number line. To find the distance between them, we subtract -172 from -69 (i.e., -69 - (-172)). This can be simplified by changing the subtraction to addition: -69 + 172.
Now, we can add the numbers: -69 + 172 = 103. So, the distance between -172 and -69 on the number line is 103 units.
