Persamaan suatu garis yg melalui titik (-2,-4) dan titik (-3,-4) adalah​

Jawaban:

8x + y + 20 = 0

Penjelasan dengan langkah-langkah:

(x1, y1) = (-2, -4)

(x2, y2) = (-3, 4)

(y – y1) / (y2 – y1) = (x – x1) / (x2 – x1)

(y – (-4) / (4 – (-4) = (x – (-2) / (-3 – (-2)

(y + 4) / (4 + 4) = (x + 2) / (-3 + 2)

(y + 4) / 8 = (x + 2) / -1

-1 . (y + 4) = 8 . (x + 2)

-1y + (-4) = 8x + 16

-y – 4 = 8x + 16

8x + y + 16 + 4 = 0

8x + y + 20 = 0
