The midpoint of a line segment with endpoints at (3,-1) and (8, -4) is
![\left((11)/(2),-(5)/(2)\right)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8opeldb854weo41ncui1nzdikvgysj20rp.png)
Solution:
We have been given 2 end points of a line which are: (3,-1) and (8, -4)
The midpoint of a line segment is half way from both the ends of the line segment.
The formula for midpoint for the two points
is given as:
![\text {Midpoint}=((x_(1)+x_(2))/(2), (y_(1)+y_(2))/(2))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/hbjgmy9upedpwzzukz9he2wyjcz2iyh6ak.png)
Here P(3, -1) and Q(8, -4)
![\text { So } x_(1)=3 ; x_(2)=8 ; y_(1)=-1 ; y_(2)=-4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ur7y6jo9fkmzw046b1fqahlscfird29qen.png)
Plugging in values in above formula, we get
![\begin{array}{l}{\text {Midpoint}=((3+8)/(2), (-1-4)/(2)})\\\\ {\text {Midpoint}=((11)/(2), (-5)/(2)})\end{array}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7sxuikloip09q1b37fo2gklb4hgg944rkl.png)
Hence, the midpoint of the line segment is
![\left((11)/(2),-(5)/(2)\right)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/8opeldb854weo41ncui1nzdikvgysj20rp.png)
