Question

The mid-point of line segment AB is (0,4). If the co-ordinates of B are (-2,3) then the co-ordinates of A are

Answer 1

Answer:

If the coordinates of B are (-2, 3), then the coordinates of A are. ⇒a-2=0andb=8-3⇒a=2,b=5. ∴ the point A is (2, 5).

Answer 2

Answer:

x=2 ,y=5

Step-by-step explanation:

let us suppose that the coordinate of point A is (x,y) and as the mid point of AB is (0,4) means the line AB on division in 1:1 gives us the mid point of line . therefore , 0= (-2+x)/2 , 4= ( 3+y)/2

hence x=2 and y=5
