Question

Can you check this one question, Please?

If point C is the Midpoint of Line Segment AB, what is the coordinate of B?

B= ? C=(1,4) A=(5,5)

(–4, 4)

(–4, 1)

(–2, 1)

(–3, 3)

I think it's (-4,1)

Answer 1

Anyways in general

midpoint=\[\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\]

Answer 2

so equate C to this equation let \[(x_1,y_1)=(5,5)\]

\((x_2,y_2) =B\)

Solve for B

Answer 3

can you do that ?

Answer 4

would (x2,y2) be (1,4)?

Answer 5

can you show ur working ?

Answer 6

i will check that

Answer 7

It's more of part guess, I'm not sure how to work it. Because (x1,y1)= (5,5), which was the first coordinate, and since the coordinate pair for C is the 2nd pair I more of assumed that's what that was.

Answer 8

using midpoint formula
