Option A:
(2, 3)
Option B:
(1,3)
Option C:
(3,2)
Option D:
(1,2)
Jamb Maths Solution:
$\begin{align} & \text{Midpoint of a line segment is given as} \\ & (x,y)=\left( \tfrac{{{x}_{1}}+{{x}_{2}}}{2},\tfrac{{{y}_{1}}+{{y}_{2}}}{2} \right) \\ & (x,y)=\left( \tfrac{3-1}{2},\tfrac{-4+10}{2} \right)=(1,3) \\\end{align}$
