What does the inequality k < 3 represent on a number line?

Back

All values of k that are less than 3, represented by an open circle at 3 and a line extending to the left.

What does the inequality b ≤ -2 mean?

Back

All values of b that are less than or equal to -2, represented by a closed circle at -2 and a line extending to the left.

Front

What is the difference between < and ≤ in inequalities?

Back

< means 'less than' and does not include the endpoint, while ≤ means 'less than or equal to' and includes the endpoint.
