We found that Choices B and E have the same constant of proportionality as shown in the given graph.
What is the constant of proportionality?
Two values x and y are said to be in a proportional relationship
if x=ky, where x and y are variables and k is a constant.
The constant k is called the constant of proportionality.
In A and B we can see that if the point (x, y) = (8, 6) marked on the first graph works in the given equation.
A
6y = 8x
6(6) = 8(8)
Thus, it is FALSE
B
y = (3/4)x
6 = (3/4)8
It is True
C) By Comparing this graph to the given graph. They don't match.
D) We can see that the point (x, y) = (3, 4) lies above the line on the given graph.
E) Here, also The point (x, y) = (4, 3) lies on the given graph.
Hence, Choices B and E have the same constant of proportionality as shown in the given graph.
