A regression model was fitted to data. The slope of the model was b=2.25 and the intercept was a=5.33. Let y be the response and x be the explanatory variable. Match the observations to the residuals:

x = 6.4, y = 8.3
x = 1.8, y = 1.5
x = 3.3, y = 5.5

Residual = -7.88

Residual = -11.43

Residual = -7.255
