What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables. The solution is the set of all points that satisfy all inequalities in the system.

How do you graph a system of inequalities?

Back

To graph a system of inequalities, first graph each inequality as if it were an equation. Then, shade the appropriate region for each inequality. The solution is where the shaded regions overlap.

What does it mean for a point to be a solution to a system of inequalities?

Back

A point is a solution to a system of inequalities if it satisfies all inequalities in the system, meaning it lies in the shaded region of the graph.

What is the difference between a solution and a non-solution in a system of inequalities?

Back

A solution satisfies all inequalities, while a non-solution does not satisfy at least one inequality.

Front

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 is the set of values that satisfy all equations in the system.

How do you solve a system of equations graphically?

Back

To solve a system of equations graphically, graph each equation on the same coordinate plane. The point(s) where the graphs intersect represent the solution(s) to the system.

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

Back

A system of equations has no solution if the graphs of the equations are parallel and never intersect.

Front

What does it mean if a system of equations has infinite solutions?

Back

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

Front

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 equations are satisfied, the point is a solution.

What is the significance of the solution set in a system of inequalities?

Back

The solution set represents all possible solutions that satisfy the inequalities, often visualized as a shaded region on a graph.
