Hi all, I am struggling to finish this problem and was seeing if anyone could help me.
There are two circles.
Circle 1 has a center at (2,4), and radius 4.
Circle 2 has a center at (14,9) and radius 9.
I need to find the equation for common tangent line of these two circles. The circles touch so there is just one exterior tangent line.
Any help is appreciated, Thanks.
