This graph displays two lines and the corresponding regions of inequalities. The blue solid line represents the line equation y = x + 4, and the red dashed line represents the line equation y = -x - 1. The shaded blue region represents the intersection of the solution sets for the two inequalities.

We can determine the direction of the inequalities by analyzing the positioning of the shaded region. For the blue solid line, the shaded region is above the line, which m...
