Question

1- Determine as coordenadas do ponto médio:
a) A(5,-1); B(7,-9).

b) A(4,5); B(-8,-11).

c) A(-6,4); B(-4,8).

d) A(-1,5); B(-9,-15)​.

Answer 1

Explicação passo-a-passo:

a) A(5,-1); B(7,-9).

x=(5+7)/2=12/2=6

y=(-1-9)/2=-10/2=-5

M( 6 ; -5)

b) A(4,5); B(-8,-11).

x=(4-8)/2=-4/2=-2

y=(5-11)/2=-6/2=-3

M(-2 ; -3)

c) A(-6,4); B(-4,8).

x=(-6-4)/2=-10/2=-5

y=(4+8)/2=12/2=6

M( -5 ; 6)

d) A(-1,5); B(-9,-15).

x=(-1-9)/2=-10/2=-5

y=(5-15)/2=-10/2=-5

M( -5 ; -5 )
