Answer:
432 (b)
Step-by-step explanation:
The proportional graph that corresponds to M = 3n is: Graph C.
<h3>What is a Proportional Graph?</h3>
The constant of proportionality, k, of a proportional graph is given as, y/x. The graph is expressed by the equation, y = kx.
The equation given, M = 3n, represents a proportional relationship where k = 3.
Using a point on graph C, (400, 1,200):
k = 1,200/400
k = 3
Therefore, the graph that corresponds to the situation is: C.
