The equation is linear and so has no vertex.
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
Linear equations are a small minority of functions.
Most functions are not like linear equations.
There are linear functions and there are quadratic functions but I am not aware of a linear quadratic function. It probably comes from the people who worked on the circular square.
No, they do not have a vertex.

Linear equations are always functions.

A linear equation is a special type of function. The majority of functions are not linear.

(0, 0), of course. No linear term.
(0, 0) of course! No linear term! Review you vertex manipulation again.
