Solving Systems of Linear Inequalities Graphically

Solving Systems of Linear Inequalities Graphically 1.2 - Solution

arrow_back Return to Solving Systems of Linear Inequalities Graphically
When determining if a given point satisfies an equation, we substitute the point into the equation and simplify. If the resulting statement is true, then the point is contained in the solution set of the equation. For systems of inequalities, we can use the same method. However, substituting the point must create true statements in every inequality in the system. Let's test to see if is a solution to the given system.
Since is greater than and less than both statements are true. Therefore, the point is contained in the solution set of the system.
