tolong dijawab ya nomor 9 dan10 . dan klw bisa pakai cara

9.
Perbandingan AC : CB = 2 : 1
Δx = 7-(-5) = 12
Δy = 8-2 = 6
Dicari titik C,
(Titik A sb x + Perbandingan sb x, Titik A sb y + Perbandingan sb y)
(-5 + 2/(2+1) x 12 , 2 + 2/(2+1) x 6)
(-5+8,2+4) = (3,6)
10.
Cari persamaan garisnya, didapat :
y = 2/3 x +1
Cari yang sesuai,
Didapat (6,5)
Karena
5 = 2/3 x 6 +1 = 4+1 = 5
