Answer:
Center is (-1, 5) and radius = 4.
Step-by-step explanation:
x^2 + y^2 + 2x - 10y + 10 = 0
This is a circle. The first thing is to complete the square:
x^2 + 2x + y^2 - 10y = -10
(x + 1)^2 - 1 + (y - 5)^2 - 25 = -10
(x + 1)^2 + (y - 5)^2 = 16 Comparing this to the standard equation:
(x - h)^2 + ( y - k)^2 = r^2
- we see that the center (h, k) is (-1, 5) and the radius r = 4.
(x +1 )^2 + (y - 5)^2 = -10+
