Using simple linear regression, calculate the trend line for the historical data. say the x axis is april = 1, may = 2, and so on, while the y axis is demand. (round your intercept value to the nearest whole number and slope value to 2 decimal places.

Given a table of historical demand for a product as follows:



The linear regression equation is given by



where:


and


We calculate the required values using the following table, where
April = 1, May = 2, and so on.



Thus,



and



Therefore, the trend line for the historical data is given by

2xy/9 is the answer to this problem
