To verify this answer: 

 Take a piece of graph paper and draw the two points.  Draw a line between them, and find point halfway inbetween.

anonymous · Answer

-2,8

anonymous · Answer

Agreed with Satellite answer (-2,10)

anonymous · Answer

$$\frac{4+(-8)}{2}=\frac{-4}{2}=-2$$
$$\frac{2+18}{2}=\frac{20}{2}=10$$

See the attached picture. 

Of course, for midpoints of very large coordinates, it's hard to draw it all, so you'll have to use the average of the coordinates.   Hopefully this will help you develop an idea of what it is we're doing with the formula.
