Graphing Inequalities on a Number Line

Front

What inequality does the number line graph represent if it has an open circle at -4 and a line extending to the left?

Back

x < -4

Front

When graphing an inequality, which symbol indicates that the endpoint is not included in the solution?

Back

< or >

Front

Which graph represents the inequality k < 3?

Back

Graph A shows k < 3.

Front

Would you use a closed or open circle to graph x < 3?

Back

Open circle.

Front

Match the graph with its inequality: If the graph has a closed dot at 11 and a line extending to the right, what is the inequality?

Back

a ≥ 11

Front

What does a closed circle on a number line indicate?

Back

The value is included in the solution.

Front

What does an open circle on a number line indicate?

Back

The value is not included in the solution.

Front

If the inequality is x ≥ 5, how would you graph it on a number line?

Back

Closed circle at 5, line extending to the right.

Front

What is the difference between ≤ and < when graphing?

Back

≤ includes the endpoint; < does not.

Front

If a number line graph shows a line extending to the left from -2 with a closed dot, what is the inequality?

Back

x ≤ -2
