Standard Form of a Line
The standard form of a linear equation is
.
The advantage of standard form is that it accommodates both horizontal lines and vertical lines .
The disadvantage is that do not stand for anything obvious (like the slope or -intercept ). In fact, they are not unique: if we double them all, we get back the same line! You can check this with the following example.
These two equations, both in standard form, represent the same line.
