Answer:

The Answer is P = (-2.5 , 1 )

Step-by-step explanation:

Let, the point is P(x,y)

then, $x=\frac{m_{1}x_{2}+ m_{2}x_{1}}{m_{1}+m_{2}}$

=> $x=\frac{5*(-1)+ 3*(-5)}{5+3}$

∴ $x=-2.5$

Again, $y=\frac{m_{1}y_{2}+ m_{2}y_{1}}{m_{1}+m_{2}}$

=> $y=\frac{5*7+ 3*(-9)}{5+3}$

∴ $y=1$

Thus, P = (-2.5 , 1 )
