Question

In an inverse variation, y = 3 when x = 8. Write an inverse variation equation that shows

the relationship between x and y.
Write the equation using a decimal or an integer.


How do I find this?

Answer 1

• y = 24/x

Explanation:

An inverse variation equation is:

• y = k/x

We have y = 3 when x = 8, find the coefficient k:

• 3 = k/8
• k = 3*8
• k = 24

The equation is:

• y = 24/x
