Question

If point C is the midpoint of , what is the coordinate of point B?

(-4,4)
(-4,1)
(-2,1)
(-3,3)

Answer 1

I tried to find a formula (which is all i need) however i can't find one.

Answer 2

Midpoint of AB*

Answer 3

Its simple....
let B=(x1,y1) A=(x2,y2) C=(x3,y3)
then we know that
by mid point formula
{(x1+x2)/2 , (y1+y2)/2}=(x3,y3)
then by substituting the points we get B=(x1,y1)

Answer 4

Option D is correct option.....
