Answer: The required value of y is 6.
Step-by-step explanation: We are given that y varies directly as x and y = 9 when
We are to find the value of y when x = 1.
According to the given information, we have
When y = 9 and we have from equation (i) that
So, equation (i) becomes
Therefore, when x = 1, we get
Thus, the required value of y is 6.
