Answer:
(1, 3)
Step-by-step explanation:
Given coordinates of 2 endpoints, G(-2, 5) and H(4, 1), midpoint of AB is calculated as shown below:
Midpoint (M) of GH, for G(-2, 5) and H(4, 1) is given as:

Let 

Thus:



Coordinates of the midpoint of GH = (1, 3).
19 x 3 = 57
57 - 9 = 48
Your answer is 19.
