Answer: second option
Explanation:
Direct variation equation has the following form:

Where "k" is the constant of variation.
In direct variation when the variable "x" increases, the variable "y" increases in proportion to "x" and when the variable "x" decreases, the variable "y" decreases in proportion to "x".
You can observe in the table that when "x" increases, "y" increases, therefore it is a Direct variation.
