Answer: (-1,-3)
Step-by-step explanation:
midpoint formula ![\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7Bx_2%2Bx_1%7D%7B2%7D%2C%5C%3A%5C%3A%5Cfrac%7By_2%2By_1%7D%7B2%7D%5Cright%29)
![\left(x_1,\:y_1\right)=\left(-3,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:-4\right)](https://tex.z-dn.net/?f=%5Cleft%28x_1%2C%5C%3Ay_1%5Cright%29%3D%5Cleft%28-3%2C%5C%3A-2%5Cright%29%2C%5C%3A%5Cleft%28x_2%2C%5C%3Ay_2%5Cright%29%3D%5Cleft%281%2C%5C%3A-4%5Cright%29)
![\left(\frac{1-3}{2},\:\frac{-4-2}{2}\right)](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7B1-3%7D%7B2%7D%2C%5C%3A%5Cfrac%7B-4-2%7D%7B2%7D%5Cright%29)
![(\frac{-2}{2},\frac{-6}{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7B-2%7D%7B2%7D%2C%5Cfrac%7B-6%7D%7B2%7D%29)
-2/2=-1
-6/2=-3
So the midpoint is (-1,-3)
