Summary

The original hand drawn graph of the data points suggests using a linear model because .

The calculations of the slopes between consecutive points suggest using a linear model because .

The slope of the hand-done model is m  and the slope of the calculator-done model is m  . The meaning of the slope in this problem is the rate of change in over .

The y-intercept of the hand-done model is ( , ) and the y-intercept of the calculator-done model is ( , ). The meaning of the y-intercept in this problem is .

The hand-done model passes through (SELECT ONE) The calculator-done model passes through (SELECT ONE) The (SELECT ONE) model best fit the data points.
