An engineer uses the line of best fit for this graph to predict that at 100 km/h, the
wind resistance will be 56 N.
What is wrong with this prediction?
Oa The data show a non-linear pattern, so linear extrapolation will lead to an
a)
error.
The line of best fit has been drawn incorrectly; there is an uneven number of
b)
data points on either side.
O c) There is nothing wrong with this prediction.
d) The engineer has made an error in reading the graph.
Wind resistance (N)
