As level maths edexcel circle question
Stuck with the 2nd part:
C has equation x^2+y^2-8x+12y+16=0
i)Find coordinates of centre C and radius of C
Line y=kx, where k is a constant, does not intersect C.
ii)Find the range of possible values of k
C has equation x^2+y^2-8x+12y+16=0
i)Find coordinates of centre C and radius of C
Line y=kx, where k is a constant, does not intersect C.
ii)Find the range of possible values of k

Try and solve for one or more intersection points (you have two simultaneous equations), then what values of k does it break down?
