Which best describes the function on the graph?

direct variation; k= -2

direct variation; k=-1/2

inverse variation; k = -2

inverse variation; k= -1/2

Option A: Direct variation ;

Explanation:

From the graph, some of the points that the line passes through are , and

Thus, direct variation is the relationship between two variable in which one is the constant multiple of the other.

The expression can be written as

Substituting the coordinate in , we get,

Also, substituting the coordinate , we get

Thus, which is direct variation.

Hence, Option A is the correct answer.
