The slope of a tangent line to the circle at any point is given by   -x / y   where  (x,y)  is the point

 

So...the slope of this line is  (-8/ 15)

 

And using the point....we have

 

y  =(-8/15) ( x -8)  + 15    simplify

 

y = (-8/15)x + 64/15 + 225/15

 

y = (-8/15)x + 289/15

 

cool cool cool
