I'm doing pretty well with PC1 but question d)i) is really getting on my nerves... can anyone help?!?!



FYI: the equation of the circle simplified is (x+1)^2+(y-6)^2=5^2


Help will be much appreciated! (Dw, it's just revision and not a serious paper that I should be doing on my own)

I haven't tried this, but what happens if you substitute y = 4 - x into the original equation for the circle and try simplifying?
