Graphing Inequalities Review (Day 2)

Front

What symbols indicate the use of a closed dot when graphing an inequality?

Back

≤, ≥

Front

When graphing the inequality x < 3, what type of circle is used?

Back

Open circle

Front

What symbols indicate the use of an open dot when graphing an inequality?

Back

<, >

Front

How do you graph the inequality r ≥ -6?

Back

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

Front

What is the solution to the inequality p - 3 > -8?

Back

p > -5; graph with an open dot at -5 and shade to the right.

Front

What is the difference between a closed dot and an open dot in graphing inequalities?

Back

A closed dot indicates that the number is included (≤, ≥), while an open dot indicates it is not included (<, >).

Front

How do you represent the inequality x ≤ 4 on a number line?

Back

Use a closed dot at 4 and shade to the left.

Front

What does the inequality y > 2 mean when graphed?

Back

Shade above the line y = 2 with an open dot at (2, y).

Front

How would you graph the inequality -3 < x < 2?

Back

Use open dots at -3 and 2, shading between them.

Front

What is the first step in solving the inequality 2p + 4 < 12?

Back

Subtract 4 from both sides to get 2p < 8.
