Don't most textbooks cost about $50? Why would our school waste money buying Focus when everyone says it's not good?

But if you want HUGE variety, go Borders

ZOMG! BORDERS IS <3 \

Maths in Focus is cheaper - that's why schools buy it.

But is it that much cheaper? The paper's got to cost something, if the content doesn't. Oh well, can't be picky, I don't have to pay for the book.

It's just cheaper cause the book is crap. That's it really.

lol thanks i would of study like the 5.3 stuff hmm that wired im so stuip i tried the online test for maths i only get around 60-70% hope i do better in the real test hmm guys i got a quick question about math

A=(5,3) b=(-1,7) c=(2,6)

find

the equation of ab and bc
If point (k,3) is on the line ab, find the valve of k

and to find the perimeter you just need to find the distance of the 3 lines and add it up right?
BTW its a triangle

With 2 points, you can find the gradient. With the gradient and one point you can use y-y1=m(x-x1) Please someone correct me if I'm wrong because I haven't done this in a while. It gives it in general form. With the equation, the rest is straightforward.
For perimeter, yeah, you find the distance of the lines and add them.
