Answer:
The answer to your question is the first option
Step-by-step explanation:
Data
C ( -3, -1)
P (1, 2)
Process
1.- Calculate the radius
r = 
r = 
r = 
r = 
r = 5
2.- Substitute the center and the radius in the equation of the circle. Remember to change the signs of the center.
Equation
(x - h)² + (y - k)² = r²
Substitution
(x + 3)² + (y + 1)² = 5²
(x + 3)² + (y + 1)² = 25
Answer:
There are an infinite number of solutions to this equation. One of which would be (-2, -1)
Step-by-step explanation:
In order to find any solution, start by picking a value for x. For the purpose of this exercise, we'll select -2. Now input that in for x and solve for y. The resulting ordered pair is a solution.
4x - 7y = -1
4(-2) - 7y = -1
-8 - 7y = -1
-7y = 7
y = -1
