Answer:
it is A because when you look at the answer they don't make sense and there is no answer D
Let set C = (1,2,3,4,5,6,7,8) and set D - (2,4,6,8).

Answer:

Step-by-step explanation:
To find the distance, we first do B - A, where B is (-6, 7) and A is (-1, 1):
(-6, 7) - (-1, 1) = (-6+1, 7-1) = (-5, 6)
Imagine it as a triangle, where the hypotenuse is the distance, and -5 and 6 are the lengths of the sides.
To find the hypotenuse (Pythagorean Theorem): 
The answer is the square root of 61.
