Front

What does a dashed line represent when graphing an inequality?

Back

It indicates that the points on the line are not included in the solution set.

Front

What is the difference between a system of equations and a system of inequalities?

Back

A system of equations has exact solutions, while a system of inequalities has a range of solutions.

Front

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

Back

Substitute the point into each inequality to see if it satisfies all conditions.

Front

What does it mean for two equations to be equivalent?

Back

They have the same solution set.
