Question

The midpoint of segment AB is (3,5). What are the
coordinates of B if the coordinates of A are (4,0)?
​

Answer 1

Answer:

(2 , 10)

Step-by-step explanation:

Let the coordinates of B be ( x , y ). Hence,

$( \frac{4 + x}{2} .\frac{0 + y}{2} ) = (3.5)$

(4 + x) ÷ 2 = 3

4 + x = 6

x = 2

y/2 = 5

y = 10

Hence, coordinates of B is (2 , 10)
