Then they are simultaneous equations.
In a dependent system of equations, the lines represented by the equations are identical; they overlap completely. This means that every point on one line is also a point on the other line. As a result, the lines appear as a single line on the graph, indicating infinitely many solutions.
Consistent dependent systems are characterized by lines that overlap, meaning they represent the same line in a graph. This occurs when the equations of the lines are equivalent, resulting in an infinite number of solutions. In such cases, every point on the line is a solution to the system of equations, indicating that the lines are not only consistent but also dependent.
A consistent system with independent equations is one in which there is at least one solution, and the equations do not overlap in their constraints, meaning that no equation can be derived from another. In such a system, the equations represent different planes (or lines in two dimensions), and they intersect at one unique point (in the case of two variables) or along a line (for three variables). This unique intersection indicates that the system has a single solution that satisfies all equations simultaneously.
When a system of linear equations is graphed, each equation is represented by a straight line on the coordinate plane. The solutions to each equation correspond to all the points on that line. The intersection points of the lines represent the solutions to the entire system; if the lines intersect at a point, that point is the unique solution. If the lines are parallel, there are no solutions, and if they overlap, there are infinitely many solutions.
They do not. A set of lines can also be considered as a system of linear equations. But the fact that there is such a system does not mean that the lines intersect.
When graphing a system of equations with infinitely many solutions, the two lines will be identical, meaning they overlap completely. As a result, they will share the same Y-intercept, which will be the point where both lines intersect the Y-axis. Therefore, the Y-intercept will be the same for both equations. This indicates that every point on the line is a solution to the system.
coincidental -Lines that share the same solution sets.

A system of equations will have no solutions if the line they represent are parallel. Remember that the solution of a system of equations is physically represented by the intersection point of the two lines. If the lines don't intersect (parallel) then there can be no solution.
That they, along with the equations, are invisible!
A system of equations with exactly one solution intersects at a singular point, and none of the equations in the system (if lines) are parallel.
The two equations represent parallel lines.
They do not. A set of lines can also be considered as a system of linear equations. But the fact that there is such a system does not mean that the lines intersect.
The solution of a system of equations corresponds to the point where the graphs of the equations intersect. If the equations have one unique point of intersection, that point represents the solution of the system. If the graphs are parallel and do not intersect, the system has no solution. If the graphs overlap and coincide, the system has infinitely many solutions.
When two lines intersect, the system of equations has exactly one solution. This solution corresponds to the point of intersection, where both equations are satisfied simultaneously. If the lines are parallel, there would be no solutions, and if they coincide, there would be infinitely many solutions.
When solving a system of equations by graphing, you will need to graph the equations on the same coordinate plane. This allows you to visually identify the point where the two lines intersect, which represents the solution to the system. If the lines intersect at a single point, that point is the unique solution; if the lines are parallel, there is no solution; and if they coincide, there are infinitely many solutions.
