Answer:
(x + 1)² + (y + 3)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² + 2x + 6y - 6 = 0
Collect the x and y terms together and add 6 to both sides
x² + 2x + y² + 6y = 6
To complete the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 6 + 1 + 9
(x + 1)² + (y + 3)² = 16
with centre = (- 1, - 3) and r =  = 4
 = 4
 
        
             
        
        
        
Answer: 
D.
Step-by-step explanation:
I graphed it. They are both not in the same qudrant because both their x and y values are opposites. This led me to believe that they were in quadrants digaonal of each other, meaning the answer was D, because if you flipped the point across the x or y axis and then flipped it again across the other axis, it would be that point. Just in case, I graphed it. Please tell me if I'm wrong :)
 
        
                    
             
        
        
        
The  expression that is equal to -4 is D 16/-4 which means  option D is correct. ( it should be noted that option D is not written properly)
<h3>Why  is that 4 is equals to  16
/-4?</h3>
In a mathematical  expression   when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.
In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence  expression that is equal to -4 is  16/-4 which is means  optionD  is correct.
Therefore, option C is correct.

Your answer should be A because none of the points are equal so they cant lie on the same line.
I hope this helped
