Persamaan garis lurus yang melalui ( -2, – 4 ) dan titik ( -5, 3 )​

Jawaban:

x1 = -2, y1 = -4

x2 = -5, y2 = 3

persamaan garis

frac{y - y1}{y 2 - y1} = frac{x - x1}{x2 - x1} \ frac{y - ( - 4)}{3 - ( - 4)} = frac{x - ( - 2)}{ - 5 - ( - 2)} \ frac{y + 4}{7} = frac{x + 2}{ - 3} \ 7(x + 2) = - 3(y + 4) \ 7x + 14 = - 3y - 12 \ 7x + 14 + 3y + 12 = 0 \ 7x + 3y + 26 = 0
