In a function, y varies directly with x, and the constant of variation is 2. which table could represent this function?

The table that could represent the function in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In this problem

y varies directly with x, and the constant of variation is

so

The equation of the direct variation is equal to

therefore

For

Find the value of y

Substitute in the equation the value of x

For
