Persamaan garis melalui titik (-3, -1) dan (-2, -2) adalah

rumus persamaan garis
[tex] \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} [/tex]
[tex](x1.y1) = ( - 3. - 1) \\ (x2.y2) = ( - 2. - 2)[/tex]
[tex] \frac{y - ( - 1)}{ - 2 - ( - 1) } = \frac{x - ( - 3)}{ - 2 - ( - 3)} [/tex][tex] \frac{y + 1}{ - 1} = \frac{x + 3}{1} [/tex]
[tex](1)(y + 1) = ( - 1)(x + 3)[/tex]
[tex]y + 1 = - x - 3 \\ y = - 3 - 4[/tex]
