Answer:                                                                                                                                 1.The number of hours you work and the amount of your paycheck.

2.The amount of weight on a spring and the distance the spring will stretch.

3.The speed of a car and the distance traveled in a certain amount of time.

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.

Answer:

The number of hours you work and the amount of your paycheck.

The amount of weight on a spring and the distance the spring will stretch.

The speed of a car and the distance traveled in a certain amount of time.
