Question
Find coordinates of the midpoint of a segment joining point $A(-1,1)$ and point $B(5,-7)$
Solution: Suppose $A\left(x_1, y_1\right)$ and $B\left(x_2, y_2\right)$
$x_1=-1, y_1=1 \text { and } x_2=5, y_2=-7$
Using midpoint formula,
$\therefore$ Coordinates of midpoint of segment $A B$
$ =\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)$
$=\left(\frac{\square}{2}, \frac{\square}{2}\right) $
$\therefore$ Coordinates of the midpoint $=\left(\frac{4}{2}, \frac{\square}{2}\right)$
$\therefore$ Coordinates of the midpoint $=(2, \square)$
