    Here is your fil with the solution https://www.dropbox.com/t/CChylr4UPd28RtxH
    Measures are automatically wrapped with CALCULATE which forces context transition. On the other hand using the formulas directly will be extremely complicated. Therefore, use can do the following:

    Predicted Income = 
    Divide (  
        RELATED ( 'Regression Table'[y] ) - CALCULATE ( [b], ALL ( 'Regression Table' ) ), 
        CALCULATE ( [m], ALL ( 'Regression Table' ) )
    )

    This shall solve your problem.

Hi Sheref_Morad 

I guess you have One to One relationship between the customer table and the regression table. In this case I think you've missed to wrap column [b] and column [m] with RELATED function.
