(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The tangent lines of two circles intersect at point (11/3,2/3). What are the two points that each tangent line touches on its respective circle?

2. Relevant equations

Circle 1: x^2 + (y-3)^2 =5

Circle 2: (x-2)^2 + (y+3)^2 = 2

3. The attempt at a solution

I found the derivatives of each circle.

Circle 1: y'(x) = -(x)/(y-3)

Circle 2: y'(x) = (2-x)/(y+5)

Do I have to use the slope-intercept equation somehow? y-yo=m(x-xo)

I'm not quite sure what do to next... :S
