Answer:

c. y = -35*x + 105

Step-by-step explanation:

Lo que demos hacer es calcular los puntos cuando x = 0 y cuando x = 3, es decir el inicio y el fin del recorrido.

Cuando x es igual 0, y = 105, por lo tanto, la función sería:

y = A*x + 105

Cuando x = 3, y = 0, por lo tanto:

0 = 3*A + 105

resolvemos para A:

3*A = -105

A = -105/3

A = -35

Por lo tanto la función es:

y = -35*x + 105

es decir, la opción c.
