How does graphing a linear system help you verify the results of solving a linear system algebraically?
You see the point the two lines cross, if they do. This is the solution to the system since it is the values of (x,y) that are on both lines The solution is a sytems is those points, if any, (x,y) that satisfy both equations. That is the same as saying they are on both lines. If you graph the equations, this is the same as saying the points that are in the intersection of the lines. This is why parallel lines represent a system with no solution and if two equations are the same line there is an infinite number of solutions.

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).

How is graphing a linear equality different from graphing linear equation?
They are the same.
When is the substitution method a better method than graphing for solving a system of linear equation?
The substitution method is often better than graphing for solving a system of linear equations when the equations are more complex or when the coefficients are not easily manageable for graphing. It is particularly advantageous when at least one equation can be easily solved for one variable, allowing for straightforward substitution. Additionally, substitution is more precise for finding exact solutions, especially when dealing with fractions or irrational numbers, where graphing may yield less accurate results. Finally, when the system has no clear intersection point or consists of more than two equations, substitution can simplify the process significantly.
How is graphing a linear inequality the same as graphing a linear equality?
Because the question is tautological. You are asking how something is the same as that very samne thing!
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.
How is graphing a linear inequality in two variables different from graphing a linear equation in two variables?
Graphing a linear equation in two variables results in a straight line, representing all the solutions that satisfy the equation, while graphing a linear inequality produces a region on one side of the line that includes all the solutions satisfying the inequality. The line itself is solid if the inequality is ≤ or ≥, indicating that points on the line are included, or dashed if the inequality is < or >, indicating that points on the line are not included. Additionally, the area shaded represents all the combinations of values that satisfy the inequality, contrasting with the single line for an equation.

a linear graph is a graph where the line is ongoing and doesn't change directions
How do you do linear functions?
By finding something who's behavior is represented by a linear function and graphing it.
