I need help with Linear Regression assignment.

I need help with the following tasks

- Without using a graphing calculator, model the data with a linear function using years 1 and 3, and using this function, predict the average number of lunches sold in 2019. Round to the nearest whole number.
- Perform the linear regression on the above data. It will be easier if you use Microsoft Excel (or an equivalent program) to perform the calculations.

I have to State the slope and y-intercept.

- What does the slope represent in this case?
- What does the y-intercept represent in this case?

- Attach the scatter plot together with the graph of the line.
