    how do i read this graph. i can't understand it. i have to find the resistance at 4 degrees. i know the answer is 66000 ohms because i got the answer off the marking scheme. all i know is that you go up on the graph from 4 degrees to find the corresponding resistance.

    It looks like they scale it differently, in terms of space used, for 0-50 on the y-axis, but it doesn't make that much difference. From 50-100 inclusive they still use 5 lines to do so. So just count up one line from 50, you are now at 60, then note how the dot is slightly above halfway between 60 and 70, and you've got your 66 (thousand).

    Ah cool, I was thinking it might have been Physics but then it didn't look like anything I'd seen before on the papers so I was a bit unsure. :p
