we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x
so
for x = 3, y = 16 -------> 16*3=48
and when
x = 6, y = 8--------> 8*6=48
the value of k=48
the inverse variation equation is
y=48/x
therefore
the answer is
y=48/x
