Iknow that inverse variation formula is y=k/x
and that if x increases y decreases.
but in the following ordered pairs it confuses me that the formula matches
-3=-48/16
-3=-3 so this should be inverse variation

but as x increases i see that y increases too.
this is not suppose to happen or am i not understanding it.
{(-624)}

clarify if this is direct variation, inverse variation or neither.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
