Answer:
D
Step-by-step explanation:
The midpoint is the average of the 2 endpoints, that is
midpoint =
=
= 2.5 → D
A. I took a educated guess
We need to find a distance between this to points.
D=√((x2-x1)²+(y2-y1)²)
For complex plain, the real part of the complex number plays a role of x,
and number of an imaginary part plays a role of y.
So,
D=√((8-2)² +(7+1)²)√ = √(36+64)=√(100)=10
Answer is D.10
