Question

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

(–4, 4)

(–4, 1)

(–2, 1)

(–3, 3)

Answer 1

look at the Rise and the Run of the AC segment
from (5, 5)
to (1, 4)
the "x" changed from 5 to 1, so a "run" of -4
the "y" changed from 5 to 4, so a Rise of -1

so, we could expect the point be to be -4, -1 less than C (1, 4)

Answer 2

So it is choice C?

Answer 3

yes

Answer 4

I got it wrong..

Answer 5

B = (1-4, 4-1) = (-3, 3)

Answer 6

right, I just notice, I misunderstood for the other one hehe
