Answer:
Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.  
Step-by-step explanation:
Given:
Let,
point S( x₁ , y₁) ≡ ( -1 , 1)  
point T( x₂ , y₂) ≡ (3 , -5)
Point M( x , y ) is the Mid point of segment ST.  
To Find:
Point M( x , y )= ?
Solution:
As Point M( x , y ) is the Mid point of segment ST.
So we have Mid Point Formula as

On substituting the given values in above equation we get

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.
