Respuesta:
[tex]y=4x-14[/tex]
[tex]y=-\frac{4}{7}x-\frac{2}{7}[/tex]
[tex]y=-4x-14[/tex]
Formula:
Ecuación de la recta que pasa por dos puntos.
[tex]y-y_1=(\frac{y_2-y_1}{x_2-x_1} )(x-x_1)[/tex]
Datos:
[tex]A(0,-14)\\B(3,-2)\\C(-4,2)[/tex]
Explicación paso a paso:
Lado AB:
[tex]y-(-14)=(\frac{(-2)-(-14)}{(3)-(0)} )(x-(0))\\\\y+14=\frac{-2+14}{3} x\\\\y=\frac{12}{3}x-14\\\\y=4x-14[/tex]
Lado BC:
[tex]y-(-2)=\frac{(2)-(-2)}{(-4)-(3)} (x-(3))\\\\y+2=\frac{2+2}{-4-3}(x-3)\\\\y=-\frac{4}{7} (x-3)-2\\\\y=-\frac{4}{7}x+\frac{4}{7}*3 -2\\\\y=-\frac{4}{7}x+\frac{12}{7}-2\\\\y=-\frac{4}{7}x+\frac{12}{7}-\frac{14}{7} \\\\y=-\frac{4}{7}x+\frac{12-14}{7}\\\\y=-\frac{4}{7}x-\frac{2}{7}[/tex]
Lado AC:
[tex]y-(-14)=\frac{(2)-(-14)}{(-4)-(0)}(x-(0))\\\\y+14=\frac{2+14}{-4}x\\\\y=-\frac{16}{4}x-14\\\\y=-4x-14[/tex]
