What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution to the system is the set of values that satisfy all equations simultaneously.

What does it mean if a system of equations has no solution?

Back

A system of equations has no solution if the equations represent parallel lines that never intersect.

How can you determine if a point is a solution to a system of equations?

Back

To determine if a point is a solution, substitute the x and y values of the point into each equation. If the point satisfies all equations, it is a solution.

What is the substitution method for solving systems of equations?

Back

The substitution method involves solving one equation for one variable and then substituting that expression into the other equation.

What is the elimination method for solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the remaining variable.

What does it mean for a system of equations to have infinitely many solutions?

Back

A system has infinitely many solutions if the equations represent the same line, meaning every point on the line is a solution.

How do you graphically represent a system of equations?

Back

A system of equations can be represented graphically by plotting each equation on the same coordinate plane and identifying the points of intersection.

What is the significance of the point of intersection in a system of equations?

Back

The point of intersection represents the solution to the system, where the values of the variables satisfy all equations.

What is a consistent system of equations?

Back

A consistent system has at least one solution, which can be either a unique solution or infinitely many solutions.
