Answer 1

question #1
as we can see, point \((5,-5)\) lies inside the shaded region

Answer 2

@bibby

Answer 3

as michele said, it lies in the bounds of our inequality because it's in the shaded region

Answer 4

for #2, we can cancel c and d because we know our conditions say \(y\ge4\) but they both have a point (4,3) and 3 is no greater than or equal to 4

same with a, it has a point (7,3)

Answer 5

so the answer to 2 would B?
