tlg jawab no 19 yaaaaaaaaa

Kelas 8 Matematika
Bab Persamaan Garis

(3, 0) dan (0, -2)

m1 = (y2 - y1)/(x2 - x1)
m1= (-2 - 0) / (0 - 3)
m1 = -2/-3
m1 = 2/3

m1 . m2 = -1
2/3 . m2 = -1
m2 = -1 . 3/2
m2 = -3/2

(3,0)

y - y1 = m (x - x1)
y - 0 = (-3/2) . (x - 3)
2y = -3x + 9
3x + 2y = 9

C.3x + 2y = 9
Semoga membantu
