Answer:

To find the value of y when x is 6, we can use the concept of direct proportionality and the given information.

Given:

y = 63 when x = 9

We can set up a proportion using the direct proportionality relationship:

y/x = k

where k is the constant of proportionality.

Substituting the given values:

63/9 = k

Simplifying:

7 = k

Now we can use the value of k to find y when x is 6:

y/6 = 7

To isolate y, we can cross multiply:

y = 6 * 7

Calculating:

y = 42

Therefore, when x is 6, y is 42.
