the constant value u take it from the Coefficients table, first...
Secondly, the constant value is also in the equation:
y= a*x + b, where a is the slope and b is the constant.

Good luck, good night and good morning!

in Y'= bx+a

i mean :
Y' is what we expect to find(it Yprime)
b is the slope
x is the unit
a is the constant
but now i am confused and i can't remember clearly something he said in the class about tthe depended and the in-depended variable that we have to think about it...anybody remembers???

y is dependent on the value of x if x increases y will also increase. i know this works the other way around, but in these cases you know x and are trying to estimate y[there is residual error]

so to make it simple:
x-independent
y-dependent

get some sleep or you will be a zombie at the exam and won't remember anything.


PS: jocolor is just brilliant
