Answer:
(-12 , 2)
Explanation:
GIVEN :-
- Co-ordinates of one endpoint = (-4 , -10)
- Co-ordinates of the midpoint = (-8 , -4)
TO FIND :-
- Co-ordinates of another endpoint.
FACTS TO KNOW BEFORE SOLVING :-
Section Formula :-
Let AB be a line segment where co-ordinates of A = (x¹ , y¹) and co-ordinates of B = (x² , y²). Let P be the midpoint of AB . So , by using section formula , the co-ordinates of P =

PROCEDURE :-
Let the co-ordinates of another endpoint be (x , y)
So ,

First , lets solve for x.



Now , lets solve for y.



∴ The co-ordinates of another endpoint = (-12 , 2)
