Textbook Problem

2 ,   1 is the midpoint of A B - , in which A has coordinates ( 8 ,   10 ) . Find the coordinates of B .

To determine

To find:

The coordinates of B if A is the given point (8, 10) and the midpoint is 2, 1.

Explanation

The coordinates of A is (8, 10).

The coordinates of B is (x2, y2).

Midpoints xm,ym=2, 1

Determining coordinates of B using midpoint formula,

xm,ym=x1+x22,y1+y22

xm,ym are the midpoints.

Here,

x1, y1=(8, 10)

xm,ym=(2, 1)
