1. Yes, Spencer is correct because the point falls on a dotted line and is therefore included in the solution set. 2. Yes, Spencer is correct because the point falls in the region that has the overlap of shading.

3. No, Spencer is incorrect because the point falls on a dashed line and is therefore not included in the solution set.

4. No, Spencer is incorrect because the point falls outside of the area with the overlap of shading.
