The slides should be appropriate and relevent ,the data should be accurate .You have to find the relation (equation ) of income data over the years for not more than 5-6 years.With proper introductory slides and well explanation in easy language.Also you have to dig up the data from the internet.
You can use the formula for linear regression like y=mx+c .This project is simply for a collage student.
