Answer:

See a solution process below:

Explanation:

The formula to find the mid-point of a line segment give the two end points is:

#M = ((color(red)(x_1) + color(blue)(x_2))/2 , (color(red)(y_1) + color(blue)(y_2))/2)#

Where #M# is the midpoint and the given points are:

#(color(red)(x_1), color(red)(y_1))# and #(color(blue)(x_2), color(blue)(y_2))#

Substituting the values from the points in the problem gives:

#M_(A-B) = ((color(red)(-9) + color(blue)(-1))/2 , (color(red)(2) + color(blue)(-8))/2)#

#M_(A-B) = ((-10)/2 , (-6)/2)#

#M_(A-B) = (-5, -3)#
