The midpoint #= (-2.5 , 3)#

The coordinates are:
#P (-4,-1) = color(blue)(x_1 , y_1#

#Q (-1 , 7) = color(blue)(x_2 , y_2#

The midpoint is calculated using formula:

Midpoint #= (color(blue)((x_1 + x _2) / 2 , (y_1 + y _2)/2))#

#= (( -4 + (-1)) / 2 , (-1 + 7) /2)#

#= ((-5) / 2 , (6) /2)#

#= (-2.5 , 3)#
