Write an Equation for a Line of Best Fit

The video tutorial explains how to determine the line of best fit for a scatter plot. It begins by introducing the concept and then guides viewers through drawing the line, ensuring it fits snugly with the data. The tutorial then explains how to identify the slope and y-intercept in the slope-intercept form (y = mx + b). Finally, it demonstrates how to choose the correct equation for the line of best fit by analyzing the slope and y-intercept, concluding that the answer is option D.

Why can option B not be the correct answer for the line of best fit?

Explain how you verified that the slope of the line is 1/2.
