tolong dong dijawab yg bener

→ Garis
-2x + 3y = -6
2x - 3y = 6
3y = 2x - 6

→ [ m = 2/3 ]

→ x1 = -6

3y = 2x - 6
3y = 2 (-6) - 6
3y = -12 - 6
3y = -18
y = -18/3
[ y1 = -6 ]

y - y1 = m (x - x1)
y - (-6) = 2/3 (x - (-6))
y + 6 = 2/3 (x + 6)
y + 6 = 2/3x + 4
y + 6 - 4 = 2/3x
y + 2 = 2/3x
y - 2/3x + 2 = 0 → { Dikali 3 }
3y - 2x + 6 = 0
