Question

The midpoint of AB is (6, 3). If the coordinates of A are (4, -2),

what are the coordinates of B?

Answer 1

Explanation:

M(6,3)

A(4,-2)⇒A(x1,y1) just incase you understand

B(x2,y2),Now I will use the midpoint formula

`M((x1+x2)/(2) ,(y1+y2)/(2) )\\=((4+x2)/(2) ,(-2+y2)/(2) )\\=separate(x)\\(4+x2)/(2) =6\\4+x2=12\\x2=12-4\\x2=8\\\\(-2+y2)/(2) =3\\-2+y2=6\\y2=3+2\\y2=5`

B(8,5)

Answer 2

(2,5) should be your answer because 4+2=6 and -2+5=3
