Question

Find the midpoint of a segment whose endpoints are (5,8) and (-3,10) ?

Answer 1

The fromula of a midpoint between (a, b) and (c, d):

$M\left(\dfrac{a+c}{2},\ \dfrac{b+d}{2}\right)$

We have (5, 8) and (-3, 10).

Substitute:

$\dfrac{5+(-3)}{2}=\dfrac{2}{2}=1\\\\\dfrac{8+10}{2}=\dfrac{18}{2}=9$

Answer: A) (1, 9)
