Answer:
4
The Problem:
Compute the distance between 8-2i and 4-2i.
Explanation:
This is equivalent to asking the distance from point (8,-2) to point (4,-2).
The nice thing about this problem is that the y-coordinates are the same which means it is just a horizontal distance. It can either be counted or just find the distance between the x's by finding the positive difference; that is do larger minus smaller.
8-4=4.
The distance between the points is 4.
