Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
what year was the graphing calculator invented
They are the same.
Put it into slope intercept form and then proceed to use your favorite method of graphing. slope-intercept: y = -3x + 1
its useful in graphing! equations, inequalities, ect pretty much graphing!
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
For a linear I can see no advantage in the table method.

Coordinate graphing is a visual method for showing relationships between numbers.
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
Graphing calculator was created in 1985.
