could you help me and explain me the answer? I would be thankful if you know how to answer and you help me, thank you

The coordintes of the given sement are,
(2, 4) and ( 2, -7).
The midpoint is halfway between the two end points:
Its x value is halfway between the two x values
Its y value is halfway between the two y values
The cooridnate of the midpoint can be calculated as,
[tex]x=\frac{x1+x2}{2},\text{ y =}\frac{y1+y2}{2}[/tex]Therefore we have,
[tex]\begin{gathered} x=\frac{2+2}{2}=\frac{4}{2}=2 \\ y=\frac{4-7}{2}=-\frac{3}{2} \end{gathered}[/tex]Thus, the correct option is D.
