In this item, it is assumed that what is asked is that if the statement is TRUE or FALSE. 

Part A:
The coordinates of the midpoint of the given endpoints of the line is equal to half of the sum of the coordinates.

Line JK
           abscissa = (-2 + 6) / 2 = 2
           ordinate = (3 + 5) / 2 = 4
Midpoint is (2, 4)

Line LN
           abscissa = (0 + 4) / 2 = 2
           ordinate = (7 + 1) / 2 = 4
Midpoint is (2, 4)

Hence, the statement is TRUE.

Part B:
              abscissa = (-8 + 4)/ 2= -2
             ordinate = (1 + 5) / 2 = 3

Midpoint  = (-2, 3)

Substituting the point to the given equation,
                  y = - x + 1
                  3 = -(-2) + 1 = 3

Thus, all statement is TRUE.
