Residuals are used to determine how the line of best fit relates to the data points

A residual value of -0.8 means, the point is 0.8 units above the line of best fit

The residual value is given as:

[tex]\mathbf{Residual = -0.8}[/tex]

When the residual value is less than 0 (i.e. negative), then the point is above the line of best fit.

So, the interpretation of a residual value of -0.8 is that, the point is 0.8 units above the line of best fit
