Front

What does a solid line represent in graphing linear inequalities?

Back

A solid line indicates that points on the line are included in the solution set.

Front

What does a dotted line represent in graphing linear inequalities?

Back

A dotted line indicates that points on the line are NOT included in the solution set.

Front

How do you determine if a point is a solution to a linear inequality?

Back

Substitute the point's coordinates into the inequality and check if it holds true.

Front

What is the first step in graphing a linear inequality?

Back

Graph the corresponding linear equation as if it were an equality.

Front

What is the significance of the shaded region in a graph of a linear inequality?

Back

The shaded region represents all the solutions to the inequality.
