For what values of k is the line y=l tangent to the circle (x-3)^2 + (y+2)^2 = 36?

Thanks!

Finished :D.

Ok, for the first part, find the midpoint of the line AB. THen, find the slope .

Now take the perpendicular slope to AB (the negative reciprocal).

Now you have the midpoint, and the slope of the perpendicular bisector. Write the equation in slope intercept form, and of course, solve for b. Show that the point P is on that line.

I dont understand the second part.
