Problem
The table below gives the results of a braking test.
Using the relationship between these data points, estimate
the stopping distance required for a vehicle traveling at
55 kph.
A hand-drawn scatter plot of these data points suggest a
linear relationship. The TI-34 MultiView™ calculator uses the
least squares method to find the line of best fit,
y
'=
ax
'+
b
, for
data entered in lists.
