What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using inequality symbols such as <, >, ≤, or ≥.

Front

What does the symbol ≤ mean?

Back

The symbol ≤ means 'less than or equal to', indicating that one value is either less than or equal to another.

Front

What does the symbol ≥ mean?

Back

The symbol ≥ means 'greater than or equal to', indicating that one value is either greater than or equal to another.

When graphing inequalities, what does shading above the line indicate?

Back

Shading above the line indicates that the solutions to the inequality are greater than the line's value.

Front

When graphing inequalities, what does shading below the line indicate?

Back

Shading below the line indicates that the solutions to the inequality are less than the line's value.

Front

What type of line is used for inequalities with ≤ or ≥?

Back

A solid line is used for inequalities with ≤ or ≥ to indicate that points on the line are included in the solution set.

Front

What type of line is used for inequalities with < or >?

Back

A dotted line is used for inequalities with < or > to indicate that points on the line are not included in the solution set.

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

Back

To determine if a point is a solution, substitute the point's coordinates into the inequality and check if the statement is true.
