These are easy, we just have to average the corresponding coordinates.

First we do a few one dimension ones, the midpoint of points on a number line:

1. 9 & 6

$\dfrac{9 + 6}{2} = \dfrac{15}{2}$

2. -2 & 7

$\dfrac{-2 + 7}{2} = \dfrac{5}{2}$

3. -3 & -13

$\dfrac{-3 + -13}{2} = -8$

For the rest of these we're in 2D, the Cartesian plane.

4. (0,0), (9,3)

$\left( \dfrac{0+9}{2}, \dfrac{0+3}{2} \right) = ( \frac 9 2, \frac 3 2)$

5. (-2,1), (3,6)

$\left( \dfrac{-2+3}{2}, \dfrac{1+6}{2} \right) = ( \frac 1 2, \frac 7 2)$

6. (-3, 14), (10, -4)

$\left( \dfrac{-3+10}{2}, \dfrac{14+-4}{2} \right) = ( \frac 7 2, 5)$
