The equation for a vertical line is for a constant (or any equivalent equation).
There is no .

For not to be involved, it must be
-->
Then, the equation for the line is <---> ,

All vertical lines have equations of the form
Knowing this tells us that we need to make the value of k such that
it is the opposite of the value of the coefficient of the other expression
involving y. Therefore, we know that k must equal -2.
