Question

The variables a and b vary inversely. Use the given values for a and b to write an equation relating a and

b.

a=2; b=5​

Answer 1

xy=10

Explanation:

Vary inversely means x and y have a constant product. The graph is not a straight line. We find the product from the given set of values a=2, b=5 to get ab=10. Therefore xy=10 is the equation.
