Answer
Explanation:
Step1: Elegir un par de puntos del gráfico
Tomemos los puntos (1, 40) y (2, 80).
Step2: Calcular la constante de proporcionalidad
La constante de proporcionalidad $k$ en una relación proporcional $y = kx$ se calcula como $k=\frac{y}{x}$. Usando el punto (1, 40), $k = \frac{40}{1}=40$. También, usando el punto (2, 80), $k=\frac{80}{2}=40$.
Answer:
40
