Answer 1

Verified answer

P = (-1 5 4)
q = (2 -1 -2)
r = (3 n m)

karena P, Q, R segaris maka PQ = k*PR
yaitu
q - p = k * (r - p)
(3 -6 -6) = k*(4 n-5 m-4)
karena 3 = 4*k
maka k = 3/4

sehingga -6 = 3/4*(n - 5)
-24 = 3n - 15
n = -3

lalu -6 = 3/4*(m - 4)
-24 = 3m - 12
m = -4

jawaban = (a)

semoga jelas dan membantu
