{(x + 3)}^{2} + {(y - 5)}^{2} = 45 A (0; 11)

of the circle to the point of

trying to find the angular coefficient .

(X, Y) = (x + 3, y - 5)

X^{2} + Y^{2} = 45 & A (3, 6)

X_{0} X + Y_{0} Y = r^{2}

3 X + 6 Y = 45

3 (x + 3) + 6 (y - 5) = 45

3 x + 6 y = 66

y = - \frac{1}{2} x + 11

I hope i help
