See a solution process below:

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, y_2))#

Substituting the values from the points in the problem gives:

#M = ((color(red)(2/3) + color(blue)(1/3))/2 , (color(red)(9/2) + color(blue)(11/2))/2)#

#M = ((((color(red)(2) + color(blue)(1))/3))/2 , ((color(red)(9) + color(blue)(11))/2)/2)#

#M = ((3/3)/2 , ((20)/2)/2)#

#M = (1/2 , 10/2)#

#M = (1/2 , 5)#
