Question

V(18, -17) and W(3,9)
Find the mid points

Answer 1

`=\left((21)/(2),\:-4\right)`

Explanation:

`\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(18,\:-17\right),\:\left(x_2,\:y_2\right)=\left(3,\:9\right)\\\\=\left((3+18)/(2),\:(9-17)/(2)\right)\\\\Refine\\=\left((21)/(2),\:-4\right)`
