graph{y + |x| < 3 [-10, 10, -5, 5]}

Explanation:

Plot the graph y = x + 3 until (0,3), then plot y = -x + 3 from (0,3). The inequality plot is the area these two linear plots shade. As the inequality is a < b and not a <= b, the lines that belong to both linear functions are not included in the inequality plot.
