It is the line

#### Explanation:

This the 3rd quadrant, therefore, we must restrict x and y to be less than 0 , when we substitute

Take the tangent of both sides:

The tangent "undoes" its inverse and substitute 1 for

Multiply both sides by x:

We dropped the restriction on y, because it is, now, a dependent variable.
