and this problem where Asif of the direct variation of two variables, means that this is a linear function. To do this, we'll need to look at the definition of a direct variation for a direct variation of two variables and must be true that the ratio between two variables is constant. This is also this also must be true for a linear function, So a direct creation of two variables is a linear function.
