Answer:
An inverse variation is something of the shape:
y = k/x.
Knowing that the point (5, 10) is included in this equation, we can obtain the value of k.
10 = k/5.
10*5 = k
k = 50
Then our inverse variation is:
y = 50/x.
Now we can give any value of x in order to find another point that is included in the variation, for example, if x = 5
y(5) = 50/5 = 10
then the point (5, 10) does also belong to the inverse variation.
if x = 50
y(50) = 50/50 = 1.
then the point (50, 1) does also belong to the inverse variation.
