Answer:
We conclude that the distance between the two numbers on a number line will be: 322
Step-by-step explanation:
Given the numbers
-212
-534
There can be a lot of ways to determine the distance between the two numbers on a number line like counting every number between them.
But, we can use a more efficient method in terms of determining the distance by taking the absolute value of the difference between those numbers.
so
Distance between the numbers:

Apply rule: -(-a) = a


Apply absolute rule: 

Therefore, we conclude that the distance between the two numbers on a number line will be: 322
Y/3=12 should be y=63 because 63/3=12
