Math Problem Statement
Solution
The graph shows a number line with solid dots at -6 and 4, and a shaded region between them. This suggests that the solution includes all values of between -6 and 4, inclusive.
To express this as an absolute value inequality, we want to rewrite the interval in terms of an absolute value. The midpoint between -6 and 4 is:
This midpoint, -1, will be the center of our absolute value expression. The distance from -1 to either endpoint (4 or -6) is:
Thus, the inequality can be written as:
This is the absolute value inequality that represents the shaded region between -6 and 4.

Tip:
Always check the endpoints on the number line to determine whether to use strict inequality (<) or inclusive inequality (≤) based on whether the dots are open or closed.
