Front

If the inequality symbol is ≤ or ≥, the line will be ___________.

Back

solid

Front

What does it mean when an inequality is represented by a dashed line?

Back

It indicates that the boundary line is not included in the solution set.

Front

What is the graphical representation of the inequality y > 2x + 1?

Back

The area above the line y = 2x + 1 is shaded.

Front

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included in the solution, while a dashed line indicates they are not.

Back

x > 4

Front

How do you determine if a system of equations has no solution?

Back

If the lines are parallel, they do not intersect, indicating no solution.
