---|
Linear Extrapolation involves using a linear equation to predict values that go beyond your data set. |

Above, we have rainfall data for January through April. From the information we already know, we have an equation that allows us to predict rainfall:
y = x + 3
Let's predict the rainfall for October:
y = (10) + 3
y = 13
