Question

The midpoint of segment XY is Z(6, -3). The coordinates of one endpoint are X(-1, 8). Find the coordinates of endpoint Y. MEDALS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Plug in the numbers into mid point formula.

Answer 2

UMM but would thant give me the mid point of yz i need to find y

Answer 3

\[\huge\color{red}{ (\frac{x_1+x_2}{2} ~~~,~~~\frac{y_1+y_2}{2})}\]

Answer 4

i know th formula but how do i get y

Answer 5

\[\huge\color{red}{ (\frac{-1+x_2}{2} ~~~,~~~\frac{8+y_2}{2})=(6,-3)}\]

Answer 6

\[\huge\color{red}{ \frac{-1+x_2}{2}=6 ~~~~~~\frac{8+y_2}{2}=-3}\]

Answer 7

ohhhh
14, -14

Answer 8

right

Answer 9

Oh, I was in the abthrrr

\[\color{red}{ \frac{-1+x_2}{2}=6 ~~~~~~\frac{8+y_2}{2}=-3}\]\[\color{red}{ -1+x_2=12 ~~~~~~8+y_2=-6 }\]\[\color{red}{ x_2=13 ~~~~~~y_2=-14 }\]

Answer 10

i was close,
thank you

Answer 11

Yeah you were, good job, yw!
