Can someone please help me with this?
1 answer:
Plot each of the points onto that graph given. See the attached image.
Based on the attached image I've provided, we can see that:
* point A is not in the shaded region nor on the boundary
* point B is on the boundary
* point C is not in the shaded region nor on the boundary
* point D is not in the shaded region nor on the boundary
So this is why choice B) (1,3) is the answer
Points on the boundary are allowed as the inequality sign has a "or equal to" portion
