We prepare the regression line in excel as shown below:
The table is updated as shown as:
As seen from above, the equation is Y=234.92X + 3360.3
As seen from equation and comparing with y=mx + c where m is slope
The slope of equation = 234.9
The y intercept is 3360.3
Substituting x = 19, we get Y = 7823.8.
Hence, forecasted demand in period 19 is 7823.8
