A. He should eyeball fit a line by picking a slope and approximating a y-intercept.
B. He should plug the data into his calculator and then use the STATS menu and conduct a quadratic regression.
C.He should choose two points in the data that form a line. Find the slope between them and then write the equation in point-slope form.
D. He should choose two points in the data, find the slope between them, then plug the slope and one point into y = mx + b. That answer is his line. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! regardless...always safest to us STATS menu for linear or quadratic regression
Cannot access the scatter plot..BUT if looks as if a quadratic curve would
best represent the data. ... Ans. B
