There is a procedure, not a formula, for graphing linear equations of the form
y = mx + n where m, n, are constants.
or
ax + by + c = 0 where a, b, c are constants.
The form of the equation does not reallt matter.
Select a set of values for x, say, 0, 1, 2, ... , 5.
Make a table with these values of x as one row. For each x, use the equation of the line to calculate the corresponding value of y and write it underneath the x in the table. Take each (x,y) pair from the table and mark its position on the coordinate plane (graph). Finally, join up the points with a straight line.
If you are confident enough you can use the following short cuts. If you make a mistake, though, you are sunk. With 5-6 points, a mistake will stick out and you should notice it. With only two points you will never know - until you get your poor results back!
For y = mx + n
Mark the two points (0, n) and (-n/m, 0) on a graph and join them with a straight line.
For ax + by + c = 0
Mark the points (0, -c/b), (-c/a, 0) on a graph and join the with a straight line.
The procedure, that is taught at school, is to

What is the advantages or disadvantages of solving system of linear equation by graphing?
The advantage of solving a system of linear equations by graphing is that it is relatively easy to do and requires very little algebra. The main disadvantage is that your answer will be approximate due to having to read the answer from a graph. Where the solution are integer values, this might be alright, but if you are looking for an accurate decimal answer, this might not be able to be achieved. Another disadvantage to solving linear equations by graphing is that at most you can have two unknown variables (assuming that you are drawing the graph by hand).
What is the formula for standard form in linear equations?
Ax+By=C
What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
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.
What is graphing method?
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.
What is the basic equation for graphing linear equations?
y=mx+b m is slope. slope is rise over run b is y-int
What is graphing tables and equations?
Which of the following is a disadvantage to using equations?
What are two symbolic techniques used to solve a system of linear equations in two variables?
I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.
How do you solve linear equations by graphing them?
Assuming you want to plot two linear equations, you plot the graphs of both, and look where they intersect. One way to plot a linear equation is to convert it to the form y = ax + b; in this case, a is the slope, and b is the y-intercept - the coordinates where the line crosses the y-axis.
