Solution

Para determinar la pendiente de la recta que pasa por los puntos (−1, 12) y (3, 15), se utiliza la fórmula de la pendiente:

m=y2y1x2x1 m = \frac{y_2 - y_1}{x_2 - x_1}

Donde:

  • (x1,y1)=(1,12) (x_1, y_1) = (-1, 12)
  • (x2,y2)=(3,15) (x_2, y_2) = (3, 15)

Sustituyendo los valores en la fórmula:

m=15123(1) m = \frac{15 - 12}{3 - (-1)}

Simplificando el numerador y el denominador:

m=33+1 m = \frac{3}{3 + 1} m=34 m = \frac{3}{4}

Por lo tanto, la pendiente de la recta es:

m=34 m = \frac{3}{4}
