do you know the midpoint formula?

anonymous · Answer

no i have no clue how to get the answer :(

anonymous · Answer

wait is it x = 6?

anonymous · Answer

the midpoint formula is:  $\huge (\frac{x_1+x_2}{2}, \frac{y1+y2}{2}) $
where the endpoints are (x1, y1) and (x2, y2).
since the midpoint is given to you, you'll need to work backwards to get the x coordinate of one of the endpoints..
