Question

Find the coordinates of
the missing endpoint if M
is the midpoint of AB.
A(4, -8) and M(5,-2)

Answer 1

Answer:(6,-2)

Step-by-step explanation:

M is the midpoint of AB then ,

M = $\frac{A+B}{2}$

$5=\frac{x+4}{2}$     ,     $-2=\frac{y-2}{2}$

$10=x+4$  ,      $-4=y-2$

$x=6$          ,      $y= -2$

so, B= (6,-2)
