Answer:
The Answer is P = (-2.5 , 1 )
Step-by-step explanation:
Let, the point is P(x,y)
then, ![x=\frac{m_{1}x_{2}+ m_{2}x_{1}}{m_{1}+m_{2}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bm_%7B1%7Dx_%7B2%7D%2B%20m_%7B2%7Dx_%7B1%7D%7D%7Bm_%7B1%7D%2Bm_%7B2%7D%7D)
=>![x=\frac{5*(-1)+ 3*(-5)}{5+3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%2A%28-1%29%2B%203%2A%28-5%29%7D%7B5%2B3%7D)
∴![x=-2.5](https://tex.z-dn.net/?f=x%3D-2.5)
Again, ![y=\frac{m_{1}y_{2}+ m_{2}y_{1}}{m_{1}+m_{2}}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bm_%7B1%7Dy_%7B2%7D%2B%20m_%7B2%7Dy_%7B1%7D%7D%7Bm_%7B1%7D%2Bm_%7B2%7D%7D)
=>![y=\frac{5*7+ 3*(-9)}{5+3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%2A7%2B%203%2A%28-9%29%7D%7B5%2B3%7D)
∴![y=1](https://tex.z-dn.net/?f=y%3D1)
Thus, P = (-2.5 , 1 )
