Question

The line AB has midpoint (2, 5).
A has coordinates (1, 7).
Find the coordinates of B.

Answer 1

(3,3)

Explanation:

Answer 2

(3,3)

Explanation:

To find the midpoint add the x coordinates together and divide by 2

(1+ xb)/2 = 2

1+ xb = 4

xb = 4-1

xb =3

To find the midpoint add the y coordinates together and divide by 2

(7+ yb)/2 = 5

7+ yb = 10

yb = 10-7

yb =3
