The inequality determines solid line and bottom shaded region under this line.
The inequality determines dotted line and top shaded region under this line.
The intersection of these two regions is the solution set to the system of two inequalities.
Points A, C, D and K belong to this region.
Answer:
D
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(3, - 2) and (x₂, y₂ ) = D(7, - 8)
CD =
=
=
= ≈ 7.2 → D
