Answer:
The midpoint of the line segment D = ( 4, 6)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given points are A(8,7) and B(0,5)
The midpoint of line segment overline AB
Let 'D' be the midpoint of AB
![D= (\frac{x_{1} + x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )](https://tex.z-dn.net/?f=D%3D%20%28%5Cfrac%7Bx_%7B1%7D%20%2B%20x_%7B2%7D%20%7D%7B2%7D%20%2C%20%5Cfrac%7By_%7B1%7D%20%2By_%7B2%7D%20%7D%7B2%7D%20%29)
![D = (\frac{8+0}{2} , \frac{7+5}{2} )](https://tex.z-dn.net/?f=D%20%3D%20%20%28%5Cfrac%7B8%2B0%7D%7B2%7D%20%2C%20%5Cfrac%7B7%2B5%7D%7B2%7D%20%29)
![D = (\frac{8}{2} , \frac{12}{2} )](https://tex.z-dn.net/?f=D%20%3D%20%20%28%5Cfrac%7B8%7D%7B2%7D%20%2C%20%5Cfrac%7B12%7D%7B2%7D%20%29)
