what if X is a minus figure? or Y has been worked out?

From what I remember, the example in the exam had the X and Y value already and asked to use linear regression to complete the next quarter of the rolling forecast

I have looked at the page mentioned – however this doesn’t really clear anything for me. i get the formula y = a+bx. But is there an example I can work this against?

Am I saying if A is 5
B is 10
and X is 130

I do 130 x 10 = 1300
plus the value of A, this would be 1305?
