Estimating lines of best fit
When we display data on scatter plots, we often see trends. Sometimes these trends are linear, meaning that the data roughly follows the path of a line.
Given a random assortment of points, draw a line of best fit through them.
Given a scatter plot, can you estimate the slope of the line of best fit that goes through the data points?
Practice estimating the equation of a line of best fit through data points in a scatter plot. Then, use the equation to make a prediction.
Practice explaining the meaning of slope and y-intercept for lines of best fit on scatter plots.
