Graphing Inequalities {Practice}

Front

What symbols do you use a closed dot when graphing an inequality?

Back

≤, ≥

Front

What inequality does the number line graph represent if it shows an arrow pointing left from -4?

Back

x < -4

Front

When graphing b ≤ 6, would you use an open or closed circle?

Back

closed

Front

Which graph matches the inequality n < -2?

Back

Graph A (the one showing values less than -2).

Front

What inequality does the number line graph represent if it shows an arrow pointing right from 3?

Back

x ≥ 3

Front

What does an open circle on a number line indicate?

Back

The value is not included in the solution (e.g., x > 3).

Front

What does a closed circle on a number line indicate?

Back

The value is included in the solution (e.g., x ≤ 3).

Front

How do you graph the inequality x < 5?

Back

Draw a number line, place an open circle on 5, and shade to the left.

Front

What is the difference between x ≤ 4 and x < 4?

Back

x ≤ 4 includes 4; x < 4 does not include 4.

Front

If a number line graph shows an arrow pointing left from -1, what inequality does it represent?

Back

x < -1
