Answer:
length is (-7,-1) and radius is 6
Step-by-step explanation:
We are given the expression of the equation of a circle that is
x2 + y2 + 14x + 2y + 14 = 0.
Using completing the squares:
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal to square root of 36 equal to 6.

Step-by-step explanation:
-x, -(x+1)
-x-(x+1)=10506
x^2+x-10506=0
The point slope form is y — y1 = m(x — x1).
Given the slope (m) = -6/5, and the y-intercept of 2, we could simply plug in these values into the point-slope form.
The point-slope is:
y — 2 = -6/5(x — 0)
where (x1, y1) = (0, 2) (y-intercept)
m = -6/5

the third choice is correct
1. 11/70
2. 7/27
3. 5/77
You just have to divide both the numerator and denominator by a common factor
