Ajarin dong bagi yang tahu

Cari dulu vektor posisi A
AB = (5, 6)
B - A = (2,1)-A=(5,6) shg A = (-3,-5)
Cari vektor posisi C
AC = (7, 4)
C - A = C - (-3, -5) = (7,4) shg C = (4, -1)
Jawaban D

AB = (5,6)
B - A = (5,6)
(2,1) - A = (5,6)
A = (-3,-5)

AC = (7,4)
C - A = (7,4)
C - (-3,-5) = (7,4)
C = (4,-1)

Jawaban D
