Question

The pair of points is on the graph of an inverse variation. Find the missing value. (3, 7) and (x, 6)

Answer 1

for the inverse variation
xy =k = constant
since 3,7 lies on it,
3*7 = k
so, k =21

also since x,6 lies on xy = k
x*6 = 21
get the value of x from here :)

Answer 2

Answer 3

hartnn is right on track, and his final equation will produce the desired value (x value).

xy = k is also correct as a way of writing a function involving inverse variation; writing y=k/x may be easier for some to recognize and understand.
