Question

Find the midpoint of the segment below and enter its coordinates as an ordered pair. If necessary, express coordinates as fractions, using the slash mark (/) for the fraction bar. (-12, -3) (3, -8)

Answer 1

`=\left(-(9)/(2),\:-(11)/(2)\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(-12,\:-3\right),\:\left(x_2,\:y_2\right)=\left(3,\:-8\right)\\\\=\left((3-12)/(2),\:(-8-3)/(2)\right)\\\\=\left(-(9)/(2),\:-(11)/(2)\right)`
