The required relation whose constant of proportionality matches with the constant of proportionality given in the graph.
Given that,
A curve is shown in the graph, it is to be determined that the constant of proportionality of the curve matches one of the curves given in the options.
What is proportionality?
Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.
Here,
Constant of proportionality for the given function,
y/x = 2 / 8 = 0.25
Since the constant of proportionality of the functions mentioned in Option A, C and E matched with the given graph.
Thus, the required relation whose constant of proportionality matches the constant of proportionality is given in the graph.
