What is the midpoint of the segment shown below?
A(5,1)
B(5,1/2)
C(10,1)
D(10,1/2)

Answer: The correct option is (B) [tex]\left(5,\dfrac{1}{2}\right).[/tex]
Step-by-step explanation: We are given to find the midpoint of the line segment shown in the figure.
From the figure, we see
a line segment with co-ordinates of the endpoints (5, 4) and (5, -3).
We know that
the co-ordinates of the midpoint of a line segment with endpoints (a, b) and (c, d) is given by
[tex]M=\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]
Therefore, the co-ordinates of the line segment shown is given by
[tex]M=\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right)=\left(\dfrac{5+5}{2},\dfrac{4-3}{2}\right)=\left(5,\dfrac{1}{2}\right).[/tex]
Thus, (B) is the correct option.
