Answer 2

We are given coordinates of the end points of the a segment AB as

A(−1, 9) and B(3, 8).

`\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left((x_2+x_1)/(2),\:\:(y_2+y_1)/(2)\right)`

`\left(x_1,\:y_1\right)=\left(-1,\:9\right),\:\left(x_2,\:y_2\right)=\left(3,\:8\right)`

`=\left((3-1)/(2),\:(8+9)/(2)\right)`

`=\left(1,\:(17)/(2)\right)`

17/2 can be written as decimal 8.5.

Therefore, coordinate of the midpoint is (1, 8.5)
