Question

Which number line shows the inequality n < -1? {++ -5-4-3-2 -1 0 1 2345 {++++++ -5-4-5-2-10 1 2 395 {+++++ -5-4-5-2 -1 0 1 2 3 日 5 +++++++++ -5-4-3-2 -1 0 1254 5

Answer 1

Given:

$n\leq-1$

Since n is greater or equal to -1, we are to use a closed dot.

To draw the number line, make a closed circle at point -1, and move the red line left (because n is less than or equal to -1).

Therefore the number line that shows the inequality is the third number line.
