So again we look for the points that are within the shaded region, which is the solution set for the system of inequalities.
First, we plot (-12,0) and see whether it is in the shaded region. It is, so this is a solution.
Next, we try (1,2). This doesn't work. Neither does (0,0).
Finally, we try (-10,1). This is in the shaded region, so it is also a solution.
