Question

The mid-point of segment AB is the point P (0, 4). If the Coordinates of B are (-2, 3) then find the coordinates of A
​

Answer 1

Answer:

A: (2,5)

Step-by-step explanation:

coordinate of mid- point of AB=> P: ( 0,4)

coordinate of B : (-2,3)

let coordinate of A : ( x1,y1)

we know that if P: (x,y) , P is mid-pt

since x = (x1+x2) /2

=> 0 = [x1+(-2)] / 2

=> x1-2 = 0

=> x1 = 2

also , y = (y1+y2) /2

=> 4 = (y1+3) /2

=> y1 = 5

therefore coordinate of A : (2,5)

Hope this helps you
