Problem:
The car has a standard transmission, so it had to be put in gear by shifting three times during the 15 seonds in which the speed was being measured. The accelerator was being depressed at a constant rate during the 15-second period and then released at the same rate until the pedal was no longer being depressed.
Table, time is x, speed is y, in each an ordered pair:
(x,y),
(1,6),
(2,14),
(3,20),
(4,30)
(5,35.5)
(6,40),
(7,48),
(8,52),
(9,54),
(10, 57),
(11, 61),
(12, 65.5),
(13, 66.5),
(14, 67),
(15, 68.2),
(16, 65),
I'm supposed to graph it using a scatterplot and determine the equation of best fit. I graphed it, but I don't know how to find the equation of best fit, if you could help, (AND EXPLAIN IT), not just give me the answer, that'd be really great, thanks!
