Answer:

Step-by-step explanation:
step 1
Find the radius of the circle
we know that
The radius of the circle is the distance between the center and any point on the circle
the formula to calculate the distance between two points is equal to

we have the points
(0,0) and (0,-9)
substitute in the formula



step 2
Find the equation of the circle
The equation of the circle in center radius form is equal to

we have

substitute


10(N + 3)
= 10N + 30
Hence, the answer is A.
Answer:
The first point should be plotted at -4, then there should be a line that goes up 8 units and gives us a final destination of 4.
