The value of y is 2 when x = 6 if the relationship between x and y is y = (1/3)x because x and y vary directly.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
x and y vary directly
y ∝ x
y = kx
Plug y = 3 and
x = 9 in the above equation to get the value of k:
3 = 9k
k = 3/9 = 1/3
y = (1/3)x
Plug x = 6
y = (1/3)6
y = 2
Thus, the value of y is 2 when x = 6 if the relationship between x and y is y = (1/3)x because x and y vary directly.
