Question

The Stop-n-Shop is halfway between Janet's house (-10, -9) and thelibrary (1,7). Find the coordinates of the Stop-n-Shop: (x, y) = ( )

Answer 1

The given points are (-10, -9), and (1,7).

We have to find the midpoint, we'll use the following formula

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

We replace the given points

$\begin{gathered} M=(\frac{-10+1}{2},\frac{-9+7}{2}) \\ M=(\frac{-9}{2},\frac{-2}{2}) \\ M=(-\frac{9}{2},-1) \end{gathered}$

Therefore, the coordinates of the Stop-n-Stop are (-9/2, -1).
