Answer:
C ) 1/3
Step-by-step explanation:
In the given equation, y = 1/3x, where it represents a proportional relationship:
1/3 represents the constant of proportionality which shows that as x increases, y also increases at the same rate. The constant of proportionality in this given instance is also the rate of change, or the slope.
The constant of proportionality under the direct proportion condition is the slope of the line when plotted for two proportional constants x and y on a graph.
Therefore, the correct answer is C) 1/3.
