HOW
TO USE YOUR TI to find the best fit line.
I will show you
how to find the equation of the best fit line as well.
HERE is the problem:
4)
Students are given a toy car to study uniform motion.
During the experiment they record the distance d(m)
covered by the car as well as the time t(s). Their
measures are recorded below:
x=
time (s)
y=
distance (m)
1.0
0.32
2.0
0.80
3.0
0.95
4.0
1.18
5
1.6
A)
using your TI plot the dots B)
the graph is : linear ? quadratic ? exponential ?.... C)
trace the best fit line. D)
Find the equation of the graph :y
= _____ x + ______
The
slope is :
the
y-intercept is: E)

VOILA ! show your problem
solved + answers to your instructor . (that will be me) ___________________________________________________________________________________________
HERE IS THE MOVIE. I made
a mistake the equation of the line should be: y = 0.294 x +
0.088 and not y = 0.294 + 0.088 of course ! I was just
chekcing your attention ! CAN'T SEE it, see below !
