Respuesta :
The equation that relates x and y is y = (1/3)x if the variables x and y vary directly and x = 18, y = 6.
What is a proportional relationship?
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
The question is incomplete.
The complete question is:
The variables x and y vary directly. Use the given values to write an equation that relates x and y. x = 18 y = 6
From the question:
y ∝ x
y = kx ..(1)
k is the constant of proportionality after removing the proportional sign.
Plug x = 18 and y = 6
6 = 18k
k = 1/3
Plug the value of k in the equation (1)
y = (1/3)x
Thus, the equation that relates x and y is y = (1/3)x if the variables x and y vary directly and x = 18, y = 6.
