Answer:

S(5,1)

Explanation:

Midpoint -M(5,3)


( (x1 + x2)/(2) (y1 + y2)/(2) ) \\ m(5 \: 3) \\ 5 = (x1 + x2)/(2) \\ 5 = (5 + x2)/(2 ) \\ 5 * 2 = 5 + x2 \\ 10 = 5 + x2 \\ 10 - 5 = x2 \\ x2 = 5 \\ 3 = (y1 + y2)/(2) \\ 3 = (5 + y2)/(2) \\ 3 * 2 = 5 + y2 \\ 6 = 5 + y2 \\ 6 - 5 = y2 \\ y2 = 1 \\ meaning \: that \: the \: coordinates \: of \: the \: second \: end \: point \: are \: (5 \: 1)

hope this helps.

Answer:


(5,1)

Explanation:

Hi there!

Midpoint =
\displaystyle ((x_1+x_2)/(2),(y_1+y_2)/(2) ) where the two endpoints are
(x_1,y_1) and
(x_2,y_2)

Plug in the given information:

Midpoint = (5,3), Endpoint = (5,5)


(5,3)=\displaystyle ((5+x_2)/(2),(5+y_2)/(2) ) where
(x_2,y_2) is the other endpoint

Solve for
x_2:


\displaystyle (5+x_2)/(2) =5\\\\5+x_2 =10\\x_2 =5

Solve for
y_2:


\displaystyle(5+y_2)/(2)=3 \\\\{5+y_2}=6\\y_2=1

Therefore, the other endpoint
(x_2,y_2) is
(5,1).

I hope this helps!
