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
