Yes it can. A linear equation in the form of y=mx+b can always be graphed used the x and y intercepts.

The question does not contain an equation but an expression. An equation can have intercepts, an expression cannot.
With great difficulty because a straight line equation must contain an equality sign in order for it to be graphed onto the Cartesian plane.
There are some relationships but not all relationships are always true. Any function can be represented by an equation. But all equations are not functions. For example, y = sqrt(x) is the equation of the square root relationship which can be graphed as a parabola on its side, but it is not a function. It has slopes at each point. Some functions can be plotted as graphs but not all. A function such as f(x) = 1 when x is rational, and f(x) = 0 when x is irrational has no slope and cannot be plotted as a graph. A graph of a vertical line is not a function.
All quadratic functions with real coefficients can be graphed on a standard x-y graph. Not all quadratic functions have real roots, maybe that's what you were thinking of?
You cannot measure its length but you can measure its slope and intercepts.
