To find the distance between B' and c' , subtract the "different" numbers. B(1,6) C(1,2)What are the "different" numbers and what is their difference?

The "different" numbers in the x-coordinates of B and C are 1 and 1. The difference between these two numbers is 0.

Therefore, the distance between B' and c' is 0 units.

Are you sure this answer is correct?

I apologize for the mistake in my previous response. Let me correct that:

The "different" numbers in the y-coordinates of B and C are 6 and 2. The difference between these two numbers is 4.

Therefore, the distance between B' and c' is 4 units.
