Front

What type of line is used when graphing an inequality with the symbols < or >?

Back

A dotted line is used.

Front

What type of line is used when graphing an inequality with the symbols ≤ or ≥?

Back

A solid line is used.

Front

What does the inequality y ≥ -x - 1 represent when graphed?

Back

It represents the region above the line -x - 1, including the line itself.

Front

What does the inequality y < x + 4 represent when graphed?

Back

It represents the region below the line x + 4, not including the line.

Front

How do you determine the solution set for a system of inequalities?

Back

By graphing each inequality and finding the overlapping region.

Front

What is the solution to the system of inequalities y > -x - 1 and y ≥ x + 4?

Back

The solution is the region above the line y = -x - 1 and on or above the line y = x + 4.

Front

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

Back

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

Front

How can you tell if a point is a solution to an inequality?

Back

By substituting the point's coordinates into the inequality and checking if it holds true.

Front

What is the graphical representation of the inequality y < -2?

Back

A horizontal line at y = -2, with shading below the line.

Front

What does the intersection of two inequalities represent?

Back

The intersection represents the set of points that satisfy both inequalities.
