Tolong dong secepatnya

Answer 1

M = -a / b
M = -3 / -2
M = 3 / 2

M1 × M2 = -1
3/2 × M2 = -1
M2 = - 2/3

( 0 , -4)
x1 , y1

Rumus:

y - y1 = M2 (x - x1)
y - (-4) = -2/3 (x -0)
y + 4 = -2/3x + 0
----------------------------- × 3
3y + 12 = -2x + 0
3y = -2x + 0 - 12
3y = -2x - 12

atau dapat dijadikan:

ax + by + c = 0
2x + 3y + 12 = 0

Jadikan jawaban terbaik yaa :):):)
