Do you have any thoughts?

What's the method for finding the point of intersection of two curves?
7. I think p= square root of N/K and q=k (square root of N/K) is that irhgt?
8. What you need to do is sub in q and p into both equations as you would do and then you end up with q= N/p and and q=kp. Therefore, N/p must equal kp so N/p=kp. Then rearrange to get p squared = N/k and then p= the square root of N/k. The rest is quite simple, as you know that q=kp you sub in p to find q...
