Question 7326
there are 2 simple variations...

1. x varies directly with y --> y {{{alpha}}} x --> y = kx, where k is a constant
or
2. x varies indirectly with y --> y {{{alpha}}} 1/x --> y = k/x, where k is a constant


in type 1, as x increases, so y increases.
in type 2, as x increases, so y decreases.


Looking at your numbers...as x increases, so y increases...looks pretty "direct" to me.


So, i am assuming that y=kx is the equation form that "explains" the numbers. We need to find k. So, put in some numbers...easy as that:


24 = 6k --> k=4


So, i believe all the pairs of numbers are generated by y=4x. You check it, to confirm this: put an x value in..do you get the y-values quoted in the question?
