The line drawn for a scatter plot may not always be the line of best fit. But you can change it to a line of best fit by adjusting its y-intercept and slope. In this activity, you will change lines to better fit the data.
Part A
How could you change the slope and the y-intercept of the line in this graph to better fit the data? (Hint: Visualize what the best fit line would look
like, and then describe how to transform the existing line to that one.)
