Does substituting the point into every inequality in the system result in true statements?
No
Practice makes perfect
To determine if a 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. For systems of inequalities we can use the same method. However, substituting the point must create true statements in everyinequality in the system. Let's test the given point.
