Persamaan garis yang melalui titik (-3,5) dan (1,-4) adalah... Pake cara ya..

[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} \\ \frac{y - 5}{ - 4 - 5} = \frac{x + 3}{1 + 3} \\ \frac{y - 5}{ - 9} = \frac{x + 3}{4} \\ y - 5(4) = x + 3( - 9) \\ 4y - 20 = - 9x - 27 \\ 4y = - 9x - 27 + 20 \\ 4y = - 9x - 7 \\ 9x + 4y = - 7 \\ 9x + 4y + 7 = 0[/tex]
