klo yg ini gmn ya?? mohon pencerahannya..

Kelas 8 Matematika
Bab Persamaan Garis

y - y1 = m (x - x1)
y + 3 = (1/2) . (x + 2)
2 (y + 3) = x + 2
2y + 6 = x + 2
2y - x + 6 - 2 = 0
2y - x + 4 = 0

✩✩ B ✩✩

y - y1 = m ( x - x1 )
y - (-3) = 1/2 ( x - (-2 )
y + 3 = 1/2 ( x + 2 )
y + 3 ( 2 ) = x + 2
2y + 6 = x + 2
2y - x = -4
2y - x + 4 = 0
Jawaban : B
