Two quantities x and y vary directly. Complete the following table. also show you're workings

Answer:
see explanation
Step-by-step explanation:
Using the first 2 values for x and y given in the table, that is
x = 6 when y = 12 and x = 8 when y = 16
We can see that y = 2x or x = 0.5y, thus
Values of y are twice values of x and values of x are half the values of y
The table can then be completed using this information as
x | 6, 8, 9, 12, 16, 18, 20, 24
and
y | 12, 16, 18, 24, 32, 36, 40, 48
