If y directly varies with x, it means that y = kx, where k is a constant. We can find the value of k using the given information.
When y = 6 and x = 2, we can substitute these values into the equation y = kx:
6 = k(2)
6 = 2k
k = 6/2
k = 3
Now that we know k = 3, we can find y when x = 1:
y = kx
y = 3(1)
y = 3
Therefore, when x = 1, y = 3.
When y = 6 and x = 2, we can substitute these values into the equation y = kx:
6 = k(2)
6 = 2k
k = 6/2
k = 3
Now that we know k = 3, we can find y when x = 1:
y = kx
y = 3(1)
y = 3
Therefore, when x = 1, y = 3.
