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

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

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

$= (-2.5 , 3)$
