How stupid do i feel...

Sorry, i understand "b"... Must have forgot its b and not c the otherside of the pond... Or maybe i just didnt read it properly...

Sorry

Thanks for all that...

Could any one add the formula in plain text to find c, or the y intercept?

Is it simply y1 - y2?

Thanks

I understand that.

So how do i got a step further an calculate

a.b

or

a * b

I understand one is dot product and the other dot ???

Thanks for the reply

Thanks for that.

I came up with a solution similar to the last one, but rather than using "-" i used "*".

Is it possible to explain why the use of " - " is used as oppesed to " + " or " * ".

I just want a full understanding of the question.

Thanks
