Pythagorean Theorem is for triangles not circles.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in your given information and simplify.
(x - (- 1))² + (y - 2)² = (3)²
(x + 1)² + (y - 2)² = 9 is your equation.
Think of the inequalities as equations in the form of y=Mx+b. Notice how choices C and D match the line shown in the graph if they are seen as linear functions. Now look at the inequality. Since the shaded region is below the line, y must be less than what is input. The correct answer must be choice D.

Answer:
1 4/5 (Proper Fraction)
1 8/10 (Proper Fraction, but Not simplified)
18/10 (Improper Fraction)
Step-by-step explanation:
change to improper fraction
22/10 - 4/10 = 18/10
Simplify
18/10 = 1 8/10
Simplify again
1 4/5
