How you can obtain the solution to a system of equations by graphing?

In the same coordinate space, i.e. on the same set of axes:
-- Graph the first equation.
-- Graph the second equation.
-- Graph the third equation.
.
.
-- Rinse and repeat for each equation in the system.
-- Visually examine the graphs to find the points (2-dimension graph) or lines (3-dimension graph)
where all of the individual graphs intersect.
Since those points or lines lie on the graph of each individual graph, they are
the solution to the entire system of equations.

When solving a system of equations by graphing how is the solution found?
The solution is the coordinates of the point where the graphs of the equations intersect.
In solving a system of two linear equations or two functions by graphing what is meant by if the system is consistent or inconsistent?
A system of linear equations is consistent if there is only one solution for the system. Thus, if you see that the drawn lines intersect, you can say that the system is consistent, and the point of intersection is the only solution for the system. A system of linear equations is inconsistent if it does not have any solution. Thus, if you see that the drawn lines are parallel, you can say that the system is inconsistent, and there is not any solution for the system.
What are graphing method?
graphing method is when you graph two lines and then find the intersection which is the answer of the system of equations
What is the main disadvantage to graphing a system of equations?
The required solution may not be within the range that is plotted, and you would have to start all over again.
Describe a system of equations that would be better graphed using graphing technology?
no.
Solving the system of equations by graphing?
Graph both equations on the same graph. Where they intersect is the solution to the system of equations

How can you determine whether a system has no solutions by graphing?
If you graph the two functions defined by the two equations of the system, and their graphs are two parallel line, then the system has no solution (there is not a point of intersection).
Can you solve system of equations by graphing?
Yes you can, if the solution or solutions is/are real. -- Draw the graphs of both equations on the same coordinate space on the same piece of graph paper. -- Any point that's on both graphs, i.e. where they cross, is a solution of the system of equations. -- If both equations are linear, then there can't be more than one such point.
What are the applications of cramer's rule?
Cramer's rule is applied to obtain the solution when a system of n linear equations in n variables has a unique solution.
When graphing a system of equations what is the point of intersection called?
The points of intersection are normally the solutions of the equations for x and y
Describe a system of equations that would be better graphed using graphing technology?
no.
What is the concept of graphing system of equations?
You take each equation individually and then, on a graph, show all the points whose coordinates satisfy the equation. The solution to the system of equations (if one exists) consists of the intersection of all the sets of points for each single equation.
What is a system of linear equations that has no solution?
there is no linear equations that has no solution every problem has a solution
