You should check this before you post, as mostly the question has already been attempted before on the forum. It saves time.

Edit: Never mind, the solution's gone for some reasons. I'll give you some tips on the question if I can find the paper.

2nd Edit: Ugh, I can't remember how to do this, it's been a year since I've attempted this kind of question, I'll wait for someone else to help.

m= -2 (using y2-y1..etc)

c= 1 (from graph)

hence:

log

log

log

therefore:

y=5x^-2

i havent checked that against the answers but will do in the next 20 mins or so

edit: that's right, but you have to state

k=5, n=-2

c= 1 (from graph)

hence:

log

_{5}y = -2log_{5}x + 1log

_{5}y = log_{5}x^{-2}+ log_{5}5log

_{5}y = log_{5}5x^{-2}therefore:

y=5x^-2
