He midpoint of segment ab is (5, 3). the coordinates of point a are (1, 5). find the coordinates of point b.

B coordinate is  ( 9 ,1).

Step-by-step explanation:

Given  : The midpoint of segment AB is (5, 3). The coordinates of point A are (1, 5).

To find : Find the coordinates of point B.

Solution : We have given

Midpoint of segment AB = (5, 3).

The coordinates of point A =  (1, 5).

Mid point : .

On plugging the values.

(5,3) = .

Now on comparing x coordinates

= 5

On multiplying both number by 2

1 + = 10.

On subtracting both sides by 1.

= 9

Now on comparing y coordinates

= 3

On multiplying both number by 2

5 + = 6

On subtracting both sides by 5.

= 1

Then B coordinate is  ( 9 ,1).

Therefore,  B coordinate is  ( 9 ,1).

Therefore, B coordinate is  ( 9 ,1).
