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 advantage that the method od substitution has over the graphing method of solving system of equations?
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).
How do you graph slope on a graphing calculator?
On all of the graphing calculators, they have the graphing things on it. First to make a graph, you need an equation. when you have the equation ready, you just press the button on the top left (for the most calculaters), the "y=" button. Then you will get a lot of empty lines for you to put the equations on. After you type all the equations, you will have to press the "graph button on the top right. then you will get a graph.
How do you solve a system of linear equations by graphing?
When you are solving a system of linear equations, you are looking for the values for the unknown variables (usually named x and y) that make each equation in the system true. Instead of using algebraic substitution or elimination, you can use graphing to find the variables. If you graph each equation on the same graph, the point where the graphs cross is the answer, which should be given as an ordered pair in the form (x,y). If the graphs do not cross anywhere (for example, parallel lines) then there is no solution. If the graphs of two lines end up being the same line, then there are an infinite number of solutions. You must know how to graph a line in order to use this method.
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.
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
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).

Why use graphing to solve a system of equations?
A graph can help you understand equations better its a little way of getting used to a a problem. I used a multiplication graph when i was 10 it helped me memorize the problem.
How do you solve systems of equations by graphing?
-- Graph each equation individually. -- Examine the graph to find points where the individual graphs intersect. -- The points where the individual graphs intersect are the solutions of 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).
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.
Why do you need a graphing calculator?
Graphing calculators are true to their name: they can graph out equaitions. Letting the calculator graph out equations is a lot easier than plotting and drawing your own graph, but you do not NEED a graphing calculator. Besides that, their functions are similar to other scientific caculators.
How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
