Answer:

1. (-1,-6)

2. (6,2)

Step-by-step explanation:

Graph each inequality. Test a point in each and shade appropriately. The darkest shaded part is a solution to the set. If the points lie within this region, they are solutions. Please note they cannot land in on of the lighter shade regions or on the lines unless equal to. This means only points on the red line in the darker shaded regions are solutions.
