Question

Using the points B (4, -8) and C (-2,4) find the midpoint and distance

Answer 1

Answer:

Mid point :

$( \frac{x_{1} +x_{2}}{2} ) , ( \frac{y_{1} +y_{2}}{2} )\\(\frac{4-2}{2}), (\frac{-8+4}{2})\\ (1,-2)$

Distance

$\sqrt{(x_{2} -x_{1} )^{2}} + \sqrt{(y_{2} -y_{1} )^{2}}\\\sqrt{(-2 -4 )^{2}} + \sqrt{(4 -(-8) )^{2}}\\\\\sqrt{36}+\sqrt{144}\\\\ 6+12\\ 18$
