-            - Enter data points in the table
-            - Adjust the sliders to fit the line

+            See how different lines affect the total squared error:
+            - The data shows the relationship between house area and price
+            - Try different slopes (m) and y-intercepts (b) for the line
+            - Watch how the squared errors (orange boxes) change
+            - Lower total squared error means a better fitting line
