Question

The point (2, −6) is the midpoint of a chord of the circle: x^2 − 6x + y^2 + 10y = −14.
Find the length of the chord.

Answer 1

first, u must determine the radius and the center of circle
if given an equation of circle :
x^2 + y^2 + Ax + By + C = 0
so, the coordinate center of circle :
x=-A/2 and y=-B/2
radius (r) = sqrt (A^2/4 + B^2/4 - C)

Answer 2

thanks! :)

Answer 3

but not yet clear :)

Answer 4

lol, still working on the problem! Here's hoping!

Answer 5

i got the answer is 6sqrt(2)

Answer 6
