Question

you found that -14 is the boundary point and is also a solution to the inequality. how can you represent this on a number line?

$w + 7 \leq -7$

$w + 7 = -7$

$w = -14$

Explanation:

Step1: Understand inequality symbols

In inequalities, $\leq$ (less than or equal to) means the boundary point is included.

Step2: Recall number - line representation rules

A closed circle (or filled - in dot) is used to represent a point that is included in the solution set of an inequality.

Answer:

Use a closed circle (filled - in dot) at $- 14$ on the number line to represent that $-14$ is a solution (since the inequality is $w + 7\leq-7$ and $w=-14$ is a solution).
