For this case we have a direct variation of the form:
Where,
- <em>k: proportionality constant </em>
We must find the value of k.
For this, we use the following data:
Therefore, replacing values we have:
Rewriting:
Clearing the value of k we have:
Therefore, the direct variation equation is given by:
