What are the coordinates of the midpoint of the segment whose endpoints are A(−1, 9) and B(3, 8) ?

Mrrafil [7]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
A&({{ -1}}\quad ,&{{ 9}})\quad 
% (c,d)
B&({{ 3}}\quad ,&{{ 8}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)
\\\\\\
\left(\cfrac{{{ 3}} - {{ 1}}}{2}\quad ,\quad \cfrac{{{ 8}} + {{ 9}}}{2} \right)$
