Question

determine as coordenadas do ponto medio do segmento ab A) (0,-1) B) (-5,-5)

Answer 1

Xm = (xA + xB ), (yA + yB ) → ( 0 + (-5)), (-1 + (-5)) →  ( - 5 ), ( -6 ) →
                2                 2                 2             2               2        2

continuando: Xm = ( -5 , -3)
                                   2

Answer 2

Boa noite

A(0, -1)
B(-5, -5) 

Mx = (Ax + Bx)/2 = (0 - 5)/2 = -5/2
My = (Ay + By)/2 = (-1 - 5)/2 = -3

M(-5/2, -3)
