There needs to be at least 5 points on the graph for an accurate line, and you must label the line the original equation, which you put right next to the line. Plus, you have to draw little arrows on both ends of the line if the domain of the equation is not restricted. If it is restricted, for example, y > 4, then you make a ray, and only draw an arrow on one end of the line.

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 graphing tables and equations?
Which of the following is a disadvantage to using equations?
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.
Are linear equations and functions different?
All linear equations are functions but not all functions are linear equations.
