Question

persamaan garis yang melalui (3, -4) dan sejajar garis x - 3y + 2023 = 0 adalah ...
a. x + 3y + 15 = 0
b. x - 3y - 15 = 0
c. x + 3y - 15 = 0
d. x - 3y + 15 = 0​

Answer 1

Verified answer

(3, -4) --> x = 3 dan y = -4

Persamaan garis sejajar

[tex]x - 3y = 3 - 3( - 4) \\ x - 3y = 3 + 12 \\ x - 3y = 15 \\ x - 3y - 15 = 0 \: (b)[/tex]
