Garis berikut yang melalui titik (-3,2) adalah....
A. 5x - 3y + 9 = 0
B. 5x + 3y + 9 = 0
C. 5x + 3y + 21 = 0
D. 3x - 5y + 9 = 0

tolong yaaa.... beserta caranyaaa​

Answer 1

Jawaban:

titik (-3,2)→●-3 = x

● 2 = y

misal

A.5x - 3y + 9 = 0

5(-3) - 3(2) + 9 = 0

(-15) - 6 + 9 = 0

(-21) + 9 = 0

-12 = 0 (salah)

B.5x + 3y + 9 = 0

5(-3) + 3(2) + 9 = 0

(-15) + 6 + 9 = 0

(-15) + 15 = 0

0 = 0 (benar)
