Graphing Inequalities {Practice}

Front

What does an open circle represent when graphing inequalities?

Back

An open circle indicates that the number is not included in the solution (e.g., x < 3).

Front

What does a closed circle represent when graphing inequalities?

Back

A closed circle indicates that the number is included in the solution (e.g., x ≤ 6).

Front

How do you graph the inequality x < 3?

Back

Use an open circle at 3 and shade to the left.

Front

How do you graph the inequality r ≥ -6?

Back

Use a closed circle at -6 and shade to the right.

Front

What inequality does the number line graph with a closed circle at -4 and shading to the left represent?

Back

x ≤ -4.

Front

What inequality does the number line graph with an open circle at 2.5 and shading to the right represent?

Back

x > 2.5.

Front

When graphing b ≤ 6, what type of circle is used?

Back

A closed circle is used.

Front

When graphing x > 2.5, what type of circle is used?

Back

An open circle is used.

Front

What is the difference between x < 3 and x ≤ 3?

Back

x < 3 does not include 3 (open circle), while x ≤ 3 includes 3 (closed circle).

Front

How do you determine which graph matches a given inequality?

Back

Look for the correct circle type and shading direction based on the inequality.
