    The residual is the difference between the data point and what the predictor equation predicts. Compare y=59 to y=6.4_0.93(60).

    I think negative to show that the point is below the predictor line.

    It would be negative. The E(error/residual) = Y (actual value) - y (predicted value/estimated value) so E(residual) = 59 - [6.4 + .93(60)] = -3.2
