I made an attempt as a guess, better than nothing!

Wow, that's actually a really good way to do it! I will try my best to remember all this for the test. I need to start practicing my re-arranging because my opinion is that if you remember the formula for the correct equation most of the rest will be re-arranging to make the subject of the...

Thanks so much! I really do owe this forum a lot, and after this exam I will be answering questions that people have on here (if I can) :D:D:D Such a great community here!

So... T=200, R=200(0.43)+99.79 = R= 185.79

Not sure what happened there [tex]b=99.79[/itex]?

Well it wasn't because of the type of paper I was using, but I use a graph on the computer and it came to 0.43. So then if 120=(0.43)(47) + b Correct me if I am wrong but b=120-20.21? So would 'b' be (sounded confusing lol) 99.

So if (0.4)(47)= 18.8 then would it be b=120-18.8

Actually sorry yes It was 120, I read the wrong column..

It was 118, so then do I need to re-arrange that formula then to get b the subject?

Alright, so I worked out that my M=0.4 So y=(0.4)(47) + (b) What is B? That website that b=(y)intercept That's a little confusing because I thought we were trying to find (y) ?

Ok, so I picked two points, but what do I do with them? I looked at that link and it doesn't show what to do next :/

Oh! Such a silly mistake, I feel like a fool now !

Thanks buddy! I'll give it a go now :)

Ah ****, misuse of the formula tags, :( For some reason it won't let me go back and edit, hope you guys can understnad that :/
