Q1a.

Midpoint formula :

$m = ( \frac{x1 + x2} {2} \: \frac{y1 + y2}{2} )$

$m = ( \frac{ - 2 + 4}{2} \: \frac{3 + 6}{2} )$

$m = (1 \: \frac{9}{2} ) \: or \: (1 \: 4.5)$

Q2a.

Distance Formula :

$d = \sqrt{(x2 - x1) ^{2} + (y2 - y1) ^{2} }$

$d = \sqrt{ ( - 2 - ( - 6)) ^{2} + (1 - ( - 2)) ^{2} }$

$d = \sqrt{ {4}^{2} + {3}^{2} }$

$d = \sqrt{16 + 9}$

$d = \sqrt{25}$

$d = 5 \: units$
