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

Back

x < -4

Front

What does an open dot on a number line indicate?

Back

The value is not included in the solution set.

Front

How do you graph the inequality x > 3?

Back

Use an open dot at 3 and shade to the right.

Front

What is the difference between ≤ and < in graphing?

Back

≤ includes the endpoint (closed dot), while < does not (open dot).
