The value of y is 2/3 when x is equal to 1 if the y varies directly as x, and y = 2 when x = 3.
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.
We have a proportional relationship given between x and y:
y ∝ x
y = Kx
Plug y = 2 and x = 3 to find the value of K
2 = 3K
K = 2/3
y = 2x/3
Plug x = 1
y = 2/3
Thus, the value of y is 2/3 when x is equal to 1 if the y varies directly as x, and y = 2 when x = 3.
