The solution includes all values of x that are 5 or greater.

Front

What does the shaded region in a graph of a system of inequalities represent?

Back

The shaded region represents all the possible solutions that satisfy all inequalities in the system.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the point into each inequality; if it satisfies all, it is a solution.

Front

What is the first step in graphing a system of inequalities?

Back

Graph each inequality as if it were an equation to find the boundary lines.

Front

What does it mean if a line is dashed in a graph of inequalities?

Back

A dashed line indicates that points on the line are not included in the solution (for < or > inequalities).

Front

What does it mean if a line is solid in a graph of inequalities?

Back

A solid line indicates that points on the line are included in the solution (for ≤ or ≥ inequalities).
