EDA, Simple Linear Regression$$

In this assignment, we will use a simplified data and create a simple linear $1$c$)$ Drop features $[5$ pts$]$

Let's drop features that are unnecessary. id is not a meaningful feature. date string has been coded to sales$\_$month and sales$\_$year, so we can remove date. zipcode can be also removed as it's hard to include in a linear regression model and the location info is included in the lat and long. Drop the features id$,$ date, and zipcode and replace the df$.$
