Question

Find the midpoint of segment AG: A(12, 3) and G(8, 8).

(4, -5)
(20, 11)
(2.5, 10)
(10, 5.5)

Answer 1

(10, 5.5) is the answer

Answer 2

how is this?
take the x's and divide by 2, and take the y's and divide by 2

Answer 3

Using vectors
\[AG= \left(\begin{matrix}8-12 \\ 8-3\end{matrix}\right)= \left(\begin{matrix}-4 \\ 5\end{matrix}\right)\]
M mid point
\[AM= \left(\begin{matrix}-4 \\ 5\end{matrix}\right)/2\]
so \[M \left(\begin{matrix}12-(-2) \\ 3-(2.5)\end{matrix}\right)=\left(\begin{matrix}10\\ 5.5\end{matrix}\right)\]

Answer 4

I forgot to correct ...
12+(-2) and 3+(2.5) => 10 & 5.5
