Buatlah persamaan garis yang melalui titik a(-2, -5) dan b(3, -7).
Jawaban:
2x + 5y + 29 = 0
Penjelasan dengan langkah-langkah:
A(-2,-5) = (x1,y1)
B(3,-7) = (x2,y2)
[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} \\ \frac{y - ( - 5)}{ - 7 - ( - 5)} = \frac{x - ( - 2)}{3 - ( - 2)} \\ \frac{y + 5}{ - 2} = \frac{x + 2}{5} \\ 5(y + 5) = - 2(x + 2) \\ 5y + 25 = - 2x - 4 \\ 2x + 5y + 25 + 4 = 0 \\ 2x + 5y + 29 = 0[/tex]
