Step-by-step Solution

Para encontrar la ecuación de la recta que tiene una pendiente \( m = -5 \) y pasa por el punto \( (4, 3) \), podemos usar la forma punto-pendiente de la ecuación de la recta, que es: \[ y - y_1 = m(x - x_1) \] donde \( (x_1, y_1) \) es el punto por el que pasa la recta y \( m \) es la pendiente. Sustituyendo los valores: - \( m = -5 \) - \( x_1 = 4 \) - \( y_1 = 3 \) La ecuación queda: \[ y - 3 = -5(x - 4) \] Ahora, simplificamos la ecuación: \[ y - 3 = -5x + 20 \] Sumamos 3 a ambos lados: \[ y = -5x + 20 + 3 \] \[ y = -5x + 23 \] Por lo tanto, la ecuación de la recta es: \[ y = -5x + 23 \]

Quick Answer

La ecuación de la recta es \( y = -5x + 23 \).
