Line segment ST is located in the standard (x, y)
coordinate plane. The coordinates of endpoint S are (8, 0)
and the coordinates of endpoint T are (–4, −12). If point
M is the midpoint of segment ST, what is the x-coor-
dinate of point M ?

8
G.
6
H.
4
J.
2
K.
–2
To find the x-coordinate of point M, we can use the midpoint formula.
The midpoint formula states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints.
In this case, the x-coordinate of endpoint S is 8 and the x-coordinate of endpoint T is -4.
Therefore, the x-coordinate of point M is:
(8 + (-4))/2 = 4/2 = 2
Hence, the x-coordinate of point M is 2.
The answer choice is J. 2
