Question

what is the midpoint of the segment joining the points (4,-2) and (-8,6)

Answer 1

The midpoint of the segment is (-2, 2)

Answer 2

the midpoint of points (x1,y1) and (x2,y2) is
$( \frac{x1+x2}{2} , \frac{y1+y2}{2} )$
given
(4,-2) and (-8,6)
the midpoint is

$( \frac{4-8}{2} , \frac{-2+6}{2} )$=
$( \frac{-4}{2} , \frac{4}{2} )$=
(-2,2)
