For Q6, I found LOIP to be y=-x and when I subbed in a point on that line to xbar,ybar i got the same points.. so shouldn't that be LOIP.
for proving infinite invariant lines, I done ybar=mxbar plus c and manipulated it, factorised all of x,y and m, since c was left alone i said it can be anything, and that was it. I know it wont be full mks, but would it be 2/3??
last question, i said k=1, prism, k=-1 sheaf... and it was 4 mks, how many would i lose???
cheers and sorry for the long post.
was hoping for an a*, as these were probably the only mistakes...
