Okay wtf was that graph question, I used y=mx-c and got 10.5 or something close to that and I looked at the graph and knew that was wrong so scribbled it all out and got 2.2 but now apparently 10.5 was right? AQA could have made that a bit more convincing so that we could be a bit more confident with our working.
Crap, I used simultaneous equations and got exactly 10. Lol didn't occur to me to look at the y-intercept. So what are other people getting for this question?

someone on this forum said they got 10.56 but then a few people in my class put the answer 2.2 like me, but thinking about it surely it makes more sense the answer was around 10 because of the maths and stuff, cheeky AQA made sure the y intercept wasn't on the graph given to us

I worked out the gradient then subbed in one of the points to get the y interecept (alpha) got 10.34 then rounded down to 10 (2sf)
Was it possible to continue drawing the graph to the negative region, or was it only drawn for the positive region? If not, then how did other people solve it?
The X axis started at 200 or so. they were tricking us i think
Full unofficial mark scheme anyone? I've think I did well on paper one, but I mucked this one up. What do you think about grade boundary over both papers? approx 110/140 for an A?
