point E $(x_1,y_1) = (-2,3)$
point F $(x_1,y_1) = (1,6)$ 

The co-ordinates of midpoint(x,y) on the line segment with end-points (x1,y1) and (x2,y2) is just the average of co-ordinates, given by :
$\large  x=\frac{x_1+x_2}{2}$
$\large  y=\frac{y_1+y_2}{2}$
now,just put the values and find the co-ordinates of midpoint (x,y).

nopes,

x = (-2+1)/2 = -1/2 =....
y = (6+3)/2 = 9/2 = ...
