The inequality is
.
means that the distance between g and 0 on a number line is less than or equal to 9 units.
To make
true, substitute numbers for g that are fewer than or equal to 9 units from 0.
The absolute value inequality
is equivalent to
.
Graph the solution set for each inequality and find their intersection.
Observe the graph, the closed circle means that
are solutions of the inequality.
The solution set is
and its graph is
