Linear regression was used to find the equation yˆ=3x+1 based on given x and y values. This equation could predict the value of y for x=100, but the result may not be accurate since 100 is significantly higher than the original x values that were used to derive the equation, which ranged from -1 to 5 only.

1. 2) You are asked to leverage linear regression to find some
predicted values. Based on the given values of -1, 1, 2, 3 and 5
and the corresponding y values, you get the linear regression
equation as yˆ=3x+1. Would you feel comfortable to find the
predicted value of y for x = 100 using this equation? Why or
why not?
