Learning goals: Teacher Facing Determine which linear model is a better fit for a given data set. Interpret (orally and in writing) the rate of change and vertical intercept for a linear model in everyday language. Use technology to generate the line of best fit, and use the equation representing the linear model to predict (extrapolate) and estimate (interpolate) values not given in the data set.
