Step-by-step explanation: What Is Direct Variation?
There are many situations in our daily lives that involve direct variation.
For example, a worker may be paid according to the number of hours he worked. The two quantities x (the number of hours worked) and y (the amount paid) are related in such a way that when x changes, y changes proportionately such that the ratio remains a constant.
We say that y varies directly with x. Let us represent the constant by k, i.e.
or y = kx where k ≠ 0
If y varies directly as x, this relation is written as y ∝ x and read as y varies as x. The sign “ ∝ ” is read “varies as” and is called the sign of variation.
