Front

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

Back

Substitute the point into each inequality and check if all inequalities are satisfied.

Front

What is the significance of the boundary line in a graph of an inequality?

Back

It separates the solution region from the non-solution region.

Front

What does it mean if a boundary line is solid?

Back

The points on the line are included in the solution set.

Front

What does it mean if a boundary line is dotted?

Back

The points on the line are not included in the solution set.
