If the coordinates of point p are (0,8) and the coordinates of point q are ( 4,2), which of the following points represents the midpoint of pq ?
a) (0,2), b) (2,4), c) (2,5), d) (4,8), e) (4,10)

The coordinates of the midpoint are just the average of the endpoint coordinates ...
x-mid is the average of the end-x's, and y-mid is the average of the end-y's.

P. x = 0, y = 8
Q. x = 4, y = 2

'x' of the midpoint is the average of 0 and 4 = (1/2)(0 + 4) = 2

'y' of the midpoint is the average of 8 and 2 = (1/2)(8 + 2) = 5

The midpoint is (2, 5) .

That's choice-'c'.
