Answer:
(-1, 5)
Step-by-step explanation:
Midpoint between two points
[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]
Define the endpoints:
- [tex]\textsf{let}\:(x_1,y_1)=(-2,1)[/tex]
- [tex]\textsf{let}\:(x_2,y_2)=(0,9)[/tex]
Substitute the defined points into the formula:
[tex]\begin{aligned}\implies \textsf{Midpoint} & =\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\\\\ & =\left(\dfrac{0+(-2)}{2},\dfrac{9+1}{2}\right)\\\\& =\left(\dfrac{-2}{2},\dfrac{10}{2}\right)\\\\& =\left(-1,5\right)\end{aligned}[/tex]
Therefore, the midpoint of the segment with endpoints (-2, 1) and (0, 9) is (-1, 5).
