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.
Which of the following is a disadvantage to using equations?
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.
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.
graphing method is when you graph two lines and then find the intersection which is the answer of the system of equations
Graph both equations on the same graph. Where they intersect is the solution to the system of equations
its useful in graphing! equations, inequalities, ect pretty much graphing!
It does not matter.
The solution is the coordinates of the point where the graphs of the equations intersect.

A scientific calculator can perform difficult and complicated equations, whereas a graphing calculator is capable of displaying complicated graphed equations.
The points of intersection are normally the solutions of the equations for x and y
