Suppose you earn $9 per hour. The amount of money you earn is in direct (constant) variation with the number of hours you work. The constant of variation would be $9, and the equation of variation is p = 9h, where p is you pay, and h is hours worked.

A constant variation is something that changes the same amount consistently over time. An equation of variation is a way to express other factors affecting the variation over time.
