Persamaan garis yang melalui titik A(-2,-5) dan B(3,-7) adalah ...

(-2, -5) >> x1 = -2, y1 = -5
(3, -7) >> x2 = 3, y2 = -7

[tex] \frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1} \\ \frac{y-(-5)}{-7-(-5)} = \frac{x-(-2)}{3-(-2)} \\ \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 \\ 5y=-2x-4-25 \\ 5y=-2x-29 \\ \\ y=- \frac{2}{5} x- \frac{29}{5} [/tex]
