Finding Lines of Fit

The video tutorial introduces the concept of a line of fit, explaining its role in representing data trends on a scatterplot. It covers how to write equations for a line of fit using the slope-intercept form, emphasizing the importance of slope and y-intercept. The tutorial also includes a practical exercise on creating a scatter plot from data, drawing a line of fit, and interpreting the slope and y-intercept. The video concludes with a prediction task using the line of fit to estimate calories based on fat grams.
