Mid-point of a segment having extreme ends as (h, k) and (p, q) is given by,
[tex](\frac{h+p}{2},\frac{k+q}{2})[/tex]
If the coordinates of the extreme ends are Q(1, 6) and R(-7, 3),
Mid-point of the segment QR will be,
[tex][\frac{1+(-7)}{2},\frac{6+3}{2}]=(-3,\frac{9}{2})[/tex]
Therefore, mid point of the segment QR will be [tex](-3,\frac{9}{2})[/tex].
