Could somebody explain what exactly is for?
The general equation is also written in a weird way:
Y = A + BX
the BX are together because it supposed to be B multiply by X, B x X, but since is confusing, they write in this way BX.
Surely it could be simpler to use another letter of the alphabet, example Y = A + B x S??:ohmy:

Linear regression looks at a straight line relationship between 2 sets of data
If you knew the cost per unit on the phone and the line rental, you could say that all you would need is the number of units consumed to know the total bill.
Total cost = Line rental + (cost per unit x units consumed)
So Total cost is Y
Units consumed is X
Line rental is a and
cost per unit is b
Y = a + bXSandy
