Question

What is Direct Variation?

Answer 1

When you have a direct variation, we say that as your variable changes, the resulting value changes in the same and proportional manner.

A direct variation between `y` and `x` is typically denoted by

`y = kx`

where `k in RR`

This means that as `x` goes larger, `y` also tends to get larger.
The opposite is also true. As `x` goes smaller, `y` tend to get smaller.
