What are the prerequisites for algebra 2?
This answer will vary depending on your high school's or college's requirements; but generally, one must have a strong grasp of graphing, systems of equations, and factoring before beginning algebra 2.
What is the answer to the systems of equations 2x plus y equals 6 6x plus 3y equals 18?
2x + y = 66x + 3y = 18Usually you can use elimination, substitution, graphing, matrices, etc. to find the answer to this system. If you use any of these methods (elimination and graphing in particular) you will see that these two equations are actually the same: multiply the first equation by three and you will see what I mean.So picture it: graphing this system would essentially be drawing the same line twice. The two lines always overlap, so the equations share infinite solutions. Therefore the solution to the system is the whole line, or all the (x, y) points that satisfy 2x + y = 6.

What can systems of equations be solved by?
By elimination or substitution
What is a systems of equations that has the same solution set as another system?
They are called equivalent systems.
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.
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.
Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand?
Accuracy Graphing by hand is prone to errors, especially when working with equations that have fractional or decimal values. When graphing by hand, it can be difficult to plot points accurately, and small mistakes can lead to incorrect solutions. A graphing calculator, on the other hand, provides precise and accurate plots, minimizing the risk of errors and ensuring that the system of equations is solved correctly. Speed Graphing by hand can be time-consuming, especially if the equations involve fractions, decimals, or complex expressions. A graphing calculator can quickly plot the lines and identify the point of intersection, which represents the solution to the system. This saves significant time compared to manually plotting each point, drawing the lines, and finding where they intersect. Handling Complex Systems Some linear systems may involve equations with more complex coefficients, decimals, or large numbers. Solving these by hand can become tedious and challenging, especially if the equations have fractional values or large integers. The graphing calculator can handle these computations effortlessly and plot the solution without the need for manual calculations. Multiple Equations For systems of equations with more than two variables, graphing by hand can be nearly impossible in a two-dimensional space. While graphing two lines to find their intersection is simple, graphing three or more planes (in a 3D space) requires different tools. A graphing calculator, however, can work with multiple equations and variables, solving the system more easily and without needing a physical 3D plot. Visual Clarity Graphing by hand requires careful and precise plotting of points and lines, which can sometimes make the solution unclear or difficult to visualize, especially if the lines are close together or intersect at non-integer values. A graphing calculator provides a clear and detailed visual representation of the system, where you can quickly observe the intersection and determine the solution. Efficiency with Multiple Solutions In some cases, linear systems may have no solution (parallel lines) or infinitely many solutions (the same line), which can be difficult to identify by hand, especially if the lines are close. A graphing calculator can quickly show if the lines are parallel (no solution) or if they overlap (infinite solutions), helping you identify the type of solution without additional steps. Learning Tool For students, a graphing calculator can serve as a valuable learning tool. It allows them to focus on understanding the concept of linear systems and how to interpret their graphical representation, rather than getting bogged down in the manual process of graphing and calculation. It also allows students to experiment with different equations and see the immediate effects of changes to the system. Convenience and Ease of Use Once you input the equations into the graphing calculator, it performs all the necessary calculations and produces the graph with minimal input. This convenience makes it ideal for checking answers quickly or solving more complicated systems that would take longer to graph by hand. In Summary: A graphing calculator allows you to solve linear systems more accurately, quickly, and with greater ease compared to graphing by hand. It removes the potential for human error, saves time, and handles more complex systems of equations effortlessly. It also provides clear and immediate visual feedback, making it an ideal tool for students or anyone looking for a more efficient way to solve linear systems.
Is it possible to solve systems of equations?
very possible, unless there is something preventing them from being true, like an undefined answer. The most common ways are through substitution, graphing, and elimination.

What is the classification of a system of equations?
The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
