Question:

The markscheme:
It's not unorthodox, just a bit long winded (you could have just used the original equation x^2 + y^2 + 6x - 4y = 12).

You would get full marks.

Question:

The markscheme:
You'd get all of the marks, because you eventually got to the correct quadratic in y. From your answer to part b, it looks like your unnecessary working in a) would be needed in part b), so you'd earn the marks then, since you have used it to answer part b).
4. Easiest way to work it out is you know when it crosses the y axis; the x coordinate has to be 0; sub those 2 values into the circle equation. Factorise and they are the 2 points.
