A taxi driver records the time required to complete various trips and the distance for each trip.
The best fit line is given by the equation
y = 0.467x + 0.417, where y represents the distance
in miles, and x represents the time for the trip in
minutes.
Use the best fit line to estimate the distance for a trip
that takes 20 minutes
CORRECT!
9.757
miles
Use the best fit line to estimate the time for a trip that is
6 miles long
