Table 1 X O 1 35 7 9 y 1 3 5 6 7 7 There are two ways to use your graph to predict the values for additional data points. One method, interpolation, estimates values between data points you have plotted on your graph. Extrapolation is used to project known data into an area not known, using the known data as a guideline.
